How do you translate a dive computer display, warning or electronic dive log without turning safety-critical information into a misleading instruction? Translation of scuba dive computers demands exact handling of depth, elapsed time, no-decompression limits, stop labels, units, alarms, gas settings, device state and logbook history. One inaccurate word can misrepresent what the equipment is telling its user.
People searching for dive computer manual translation, scuba alarm meanings, NDL translation, diving logbook terminology, ascent-rate warnings or multilingual dive-computer instructions need more than a bilingual list of technical words. The crucial issue is whether a certified diver or instructor would understand the same device status and warning after reading the translation, without adding any new claim of safety.
This guide is about documentation fidelity, not how to conduct a dive. Dive computers vary by manufacturer, model, firmware, mode, gas and training context. Real-world use requires training and following the applicable manufacturer’s current instructions. Every numbered display value below is illustrative text only and is not a dive plan, exposure limit, decompression recommendation or instruction to enter the water.
The visible problem: an accurate word can still describe the wrong state
A dive computer may distinguish a no-decompression time remaining from elapsed bottom time, a safety-stop notice from a required decompression obligation, and a battery warning from a device failure. A translation that collapses two such labels may be fluent but materially unsafe. Similar problems appear in logs: a number recorded in metres cannot quietly be labelled feet, and an alarm acknowledged on screen cannot be described as a condition resolved. The first responsibility is to preserve what the source device actually reports and what it does not.
Ten first principles of safety-critical device translation
1. The device state is the core meaning
A label conveys a condition at a moment in time. Translate active, pending, acknowledged, resolved, unavailable and historical states distinctly, with the original status context intact. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
2. Measured quantities must retain units
Depth, time, pressure and temperature are different physical quantities. Preserve units and any conversion policy; do not silently treat feet and metres as equivalent numbers. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
3. NDL is not total time remaining
No-decompression limit information is distinct from elapsed dive time, remaining gas and other countdowns. A general phrase such as time left erases what is being measured. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
4. A stop label has its own role
Safety-stop reminders and decompression obligations cannot be treated as interchangeable, nor should translators imply that one always replaces the other. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
5. An alarm is not ordinary advice
Warning severity, audible or visual indicators, priority and action language need exact treatment. Weakening imperative force can hide equipment-reported urgency. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
6. Gas labels identify configurations
Air, enriched air, gas mixtures, set points and selected modes have device-specific meanings. Do not invent a gas setting or infer what a diver breathed. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
7. History is not a live instruction
A saved dive profile reports what occurred or was logged. It must not be repackaged as a current recommended procedure. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
8. The manufacturer vocabulary matters
Two computers may use different menu structures or abbreviations. Localize according to the actual model manual, not a glossary borrowed from another brand. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
9. Unknown is a legitimate status
A missing sensor reading, unpaired transmitter, low battery or unreadable screenshot may require a clear not available label. Fabricated precision is unacceptable. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
10. Human review is indispensable
A knowledgeable dive professional and language reviewer should validate safety-critical terminology against the authoritative manual. AI or translation memory cannot certify safe operation. The translator’s task is documentary: identify exactly what the device communicates and retain the same limits of knowledge. A phrase can be grammatical yet dangerously overconfident if it invents permission, suggests a medical or operational guarantee, or mislabels a measurement. Record the model-specific source for every critical term.
A twelve-stage method for multilingual display and logbook QA
Step 1: Identify exact model and revision
Record manufacturer, model, firmware, manual edition and language pair. Do not combine instructions from apparently similar devices. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 2: Capture the complete screen context
Preserve screenshot, menu path, icon, screen state, date and operating mode. A single isolated abbreviation is often ambiguous. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 3: Create a typed field inventory
Mark each term as depth, time, pressure, gas, rate, state, alarm, button label or historical log field before drafting. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 4: Protect measurements and units
Lock numerical values, decimal symbols and units; decide explicitly whether a localized display translates or converts units. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 5: Separate live warnings from logs
Record whether text appears in an active dive screen, pre-dive setup, error screen, history record or exported logbook. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 6: Map alarm severity and priority
Preserve warning type, level, repetition and acknowledgment state. Never reduce an alert to casual information because its wording feels blunt. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 7: Translate modes cautiously
Check air, nitrox, gauge, apnea or specialized settings only against the exact manual; do not generalize across devices. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 8: Identify abbreviations through documentation
Determine what NDL, TTS, PO2 and other shorthand mean for the named model. Expand terms in support text only when supported. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 9: Preserve temporal relationships
Differentiate elapsed, remaining, projected, maximum, current, previous and archived values. Tense changes can distort the device message. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 10: Run a state-transition audit
Test example transitions from normal display to warning to acknowledgment to historical log, checking that target labels still differ. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 11: Seek qualified specialist sign-off
Have a technically competent dive professional review critical terminology and a native-language reviewer test comprehension. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Step 12: Publish with clear limits
Disclose applicable model and revision, unresolved strings and legal status of the translated manual. Do not substitute the translation for training or official manufacturer directions. Treat this as an independent validation pass, not a wording suggestion. Keep the source text, screenshot, expected device state and target wording together. If the available evidence cannot justify a translation, escalate the string rather than leaving a seemingly polished phrase that may be mistaken for an authoritative instruction.
Thirty illustrative worked cases: quantities, alarms, history and settings
All screen values below are invented examples for translation review. They are not operational dive parameters, recommended exposure values or equipment instructions. Actual meanings and settings must be taken from the specified manufacturer’s current manual.
Worked case 1: Depth unit
Sample source label: DEPTH 18 m.
Misleading interpretation: Depth eighteen feet.
Fidelity-focused rendering: Depth: 18 m.
The numeral and unit jointly describe a measurement. Preserving 18 while changing metres to feet creates a different value. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Compare the exact source unit and display settings. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 2: No-decompression limit
Sample source label: NDL 12 min on a sample display.
Misleading interpretation: Twelve minutes of air left.
Fidelity-focused rendering: No-decompression time remaining: 12 min, as indicated by this sample label.
NDL and breathing-gas availability are different categories. A translator must not infer gas status from an NDL field. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.

Worked case 3: Elapsed time
Sample source label: DIVE TIME 42 min.
Misleading interpretation: Forty-two minutes permitted before surfacing.
Fidelity-focused rendering: Elapsed dive time: 42 min.
Elapsed time describes history, not a safe remaining period or recommendation. Grammar must not transform a measurement into permission. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.

Worked case 4: Maximum depth
Sample source label: MAX DEPTH 23.6 m.
Misleading interpretation: Current depth 23.6 m.
Fidelity-focused rendering: Maximum recorded depth: 23.6 m.
A maximum is a historical extreme, not necessarily the present depth. Confusing them alters profile interpretation. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Compare current and maximum fields together. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 5: Current and average
Sample source label: AVG DEPTH 11 m.
Misleading interpretation: Current depth 11 m.
Fidelity-focused rendering: Average recorded depth: 11 m.
Average, maximum and instantaneous quantities answer different questions. Removing the statistical qualifier invalidates the label. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Check the source’s AVG abbreviation. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 6: Ascent warning
Sample source label: ASCENT RATE WARNING.
Misleading interpretation: You may ascend faster now.
Fidelity-focused rendering: Ascent-rate warning; follow the device’s applicable instructions.
The source is a warning, not permission or a new procedure. The target must preserve alert status without inventing an emergency plan. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Verify alarm wording and severity in the model manual. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 7: Stop label
Sample source label: SAFETY STOP on screen.
Misleading interpretation: Required decompression obligation.
Fidelity-focused rendering: Safety-stop indication, using the manufacturer’s terminology.
A safety-stop prompt should not be relabeled as a decompression obligation, which has distinct operational meaning. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Check the exact stop category used in that mode. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 8: Decompression label
Sample source label: DECO STOP REQUIRED.
Misleading interpretation: Optional pause if convenient.
Fidelity-focused rendering: Decompression-stop requirement shown by device.
Required and optional are materially different forces. Translation must never weaken an explicit condition. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Escalate for trained specialist verification. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 9: Stop countdown
Sample source label: STOP TIMER 02:30.
Misleading interpretation: Two minutes thirty seconds of gas remaining.
Fidelity-focused rendering: Stop timer: 02:30.
The countdown belongs to the named stop-related timer, not an unrelated reserve. Its format may be minutes and seconds rather than a decimal. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.

Worked case 11: Gas mixture
Sample source label: GAS 1: O2 32%.
Misleading interpretation: Tank gas pressure 32%.
Fidelity-focused rendering: Gas 1: oxygen fraction 32%, as displayed.
A percentage of oxygen is not pressure. Translators must distinguish gas composition from cylinder measurements. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Check unit, gas number and mode context. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 12: Gas switch
Sample source label: SWITCH GAS? confirmation prompt.
Misleading interpretation: Gas switch completed.
Fidelity-focused rendering: Confirm gas switch?
A question prompt is a proposed action, not a completed state. Translators must retain its interrogative and confirmation role. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Test the menu before and after confirmation. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 13: PO2 abbreviation
Sample source label: PO2 HIGH on display.
Misleading interpretation: Tank pressure high.

A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 29: Lost pressure data
Sample source label: Tank pressure field shows ‘–‘.
Misleading interpretation: Cylinder is empty.
Fidelity-focused rendering: Pressure reading unavailable on this display.
Missing data is not a zero reading. Such an invention could alter a safety-related interpretation. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Use a clear unavailable label and consult the device documentation. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Worked case 30: Historical alarm
Sample source label: LOG: ASCENT ALARM EVENT.
Misleading interpretation: Ascent alarm is now sounding.
Fidelity-focused rendering: Recorded ascent-rate alarm event in the dive log.
The saved event describes the past. Treating it as current changes time and device state. In a safety-related interface, interpretive additions can be as harmful as omissions. The target must tell the reader what was actually displayed, including the relevant physical unit, time reference and alert status. It must not introduce an assurance that neither the equipment nor the source manual gives.
Review checkpoint: Check historical-versus-live screen context. Any ambiguous phrase should remain unresolved pending model-specific verification. A bilingual reviewer should also ask whether an ordinary reader could mistakenly take the translated label as new permission or a general-purpose diving rule.
Ten recurring translation failures and their repairs
Failure 1: Unit swap
The same number is given a different measurement unit. Repair: Lock number and unit as a pair; document any deliberate conversion. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 2: Count-down confusion
NDL, elapsed time and stop timers are all translated as time left. Repair: Identify each field’s measurement role before rewriting. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 3: Alarm softening
Required warnings become optional suggestions. Repair: Preserve imperative force, severity and manufacturer terminology. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 4: Alarm inflation
A low-battery status is described as complete sensor failure. Repair: Do not claim a state beyond the displayed condition. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 5: Mode borrowing
A word from another brand’s manual is inserted without validation. Repair: Confirm model, firmware and manufacturer lexicon. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 6: Misleading reassurance
Missing telemetry becomes a safe numeric reading. Repair: Use unavailable or error wording exactly as supported. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 7: History-to-instruction shift
Logbook durations become recommended future limits. Repair: Keep historical tense and prohibit unsupported prescriptive language. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 8: Timezone ambiguity
Log timestamps change day through silent locale assumptions. Repair: Preserve UTC offsets and source date formats. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 9: Mixed gas fields
Gas oxygen fraction is confused with pressure. Repair: Type each quantity and verify its unit. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Failure 10: Unreviewed machine translation
Automated wording is published despite contradictory alarm definitions. Repair: Require bilingual human review and qualified specialist approval. The corrective evidence should be reproducible from the actual source and manual, rather than a translator’s intuition. The editor must verify that the revision does not quietly become procedural advice, an invented safety threshold or a statement that the device has certified a condition as safe.
Practice and transfer for translators and reviewers
Exercise 1: Create a data dictionary
Make a table of 20 sample screen fields with type, unit, live/historical state and expansion source. Model review: An acceptable table makes NDL, depth, time, gas and alert fields visibly distinct. Complete the exercise using fictional documents and explicit source labels. A successful learner can explain why the translation preserves a particular quantity or device state, and can name what additional manufacturer evidence is needed before a real-world manual or interface may be released.
Exercise 2: Compare alarm force
Translate warning, caution, confirmation and acknowledgment into the target language. Model review: Check whether a reader can still tell urgent alert from ordinary menu choice. Complete the exercise using fictional documents and explicit source labels. A successful learner can explain why the translation preserves a particular quantity or device state, and can name what additional manufacturer evidence is needed before a real-world manual or interface may be released.
Exercise 3: Validate unit pairs
Mark fictional readings in metres, feet, bar, psi and percent. Model review: Preserve the specified unit on every field without converting it silently.

A successful learner can explain why the translation preserves a particular quantity or device state, and can name what additional manufacturer evidence is needed before a real-world manual or interface may be released.
Exercise 5: Handle missing telemetry
Translate three states: 0, no signal and sensor error. Model review: Ensure zero, unavailable and faulty are not collapsed into one claim. Complete the exercise using fictional documents and explicit source labels. A successful learner can explain why the translation preserves a particular quantity or device state, and can name what additional manufacturer evidence is needed before a real-world manual or interface may be released.
Exercise 6: Review a log export
Prepare a sample historical dive log with timestamps, gas labels and event markers. Model review: Separate archived data from active device prompts and preserve time reference.

Exercise 8: Run a comprehension test
Give target-language labels to a qualified diver without the original-language screen. Model review: Ask what each label reports and whether the meaning differs from the official manual; revise any mismatch. Complete the exercise using fictional documents and explicit source labels. A successful learner can explain why the translation preserves a particular quantity or device state, and can name what additional manufacturer evidence is needed before a real-world manual or interface may be released.
Frequently asked questions
Is this guide a substitute for dive training?
No. It teaches translation fidelity. A computer display or translated manual does not replace certified training, instruction or the manufacturer’s operating guidance. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
What does NDL stand for?
It commonly refers to no-decompression limit or no-decompression time information. Verify the precise label and logic for the actual computer model. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
Can I use one universal dive-computer glossary?
Use it only as a starting point. Models, modes, abbreviations and firmware versions differ, so check the exact manufacturer documentation. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
May I translate a depth number without the unit?
Not responsibly in safety-related material. The numeric value and physical unit must remain connected. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
Are safety stops and decompression stops the same?
No. They represent different concepts in dive-computer and training terminology. Avoid substituting either label for the other. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
What if a screenshot lacks model identification?
Treat it as incomplete context. Do not assign a definitive function to an ambiguous indicator without authoritative identification. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
Can a cleared alarm be called a resolved condition?
Not unless the source device confirms that state. Acknowledging a notification is not necessarily the same as ending its underlying cause. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
Should I convert metres to feet?
Only if the localization specification requires conversion and the display or document supports it. Verify accuracy and label the converted unit explicitly. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
Do historical logbook values tell me how long the next dive can be?
No. Historical values report recorded conditions and durations. They should not be repurposed as future dive limits. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
Can artificial intelligence localize alarms automatically?
It may draft strings, but specialist technical verification and real-device context checks are essential before publishing safety-critical text. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
What should a translation reviewer examine?
The reviewer should check model and revision, each numeric unit, warning priority, live-versus-historical state, terminology and user comprehension. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
What should I do when a string is ambiguous?
Document the source, request manufacturer clarification and withhold an unsupported final meaning. Do not invent precision for a safety-critical label. For real equipment, the appropriate response to uncertainty is to consult current manufacturer documentation and qualified instruction, not to infer how a diver should act from a translation example.
