Manual reflects technical status of OSTC and firmware as of August 2017.
Manual refers to OSTC standard settings; asterisk denotes non-default settings.
Details information shown on display, including depth, duration, and environmental data.
Covers gas mixture configuration, setpoints, decoplan calculation, and dive data recording.
Emphasizes diver competency, dive education, and understanding device settings for safe operation.
Outlines essential checks: dive plan, OSTC configuration, stable firmware, and battery status.
Verifies device waterproofing, secure attachment, and checks for display warnings before diving.
Advises carrying a backup system, taking surface breaks, and using the OSTC correctly.
Explains how to operate the OSTC using its buttons and navigate through menus.
Used for adjusting settings, reviewing data, and displaying general information.
Automatically activates underwater, showing dive-specific data and decompression information.
Conserves energy by entering sleep modes when inactive.
Configures the OSTC for open circuit, closed circuit, or rebreather diving with specific gas settings.
Enables apnea diving/snorkeling or using the OSTC as a simple depth gauge.
Explains the necessity and process of calibrating the tilt-compensated compass for accurate heading.
Lists information consistently shown in surface mode, like ambient pressure, clock, and battery status.
Details additional information available in the custom view, such as compass, gaslist, and desaturation diagrams.
Covers adjusting dive settings, reviewing logbook, and accessing gas setup menus.
Includes simulator, deco mode, general settings, and exit options for comprehensive control.
Accesses device information, firmware details, and initiates Bluetooth connectivity.
Configures device time, date format, and language settings for user preference.
Adjusts screen brightness, color schemes, and display orientation for optimal viewing.
Configures dive timeout, compass calibration, logbook numbering, units, and sampling rate.
Provides options to reset deco data, reboot the device, or restore factory default settings.
Selects dive mode (OC, CCR, etc.) and decompression algorithm (Bühlmann ZH-L16 or ZH-L16+GF).
Configures oxygen partial pressure limits and enables/disables safety stops for dive planning.
Adjusts gradient factors, saturation/desaturation multipliers, and last stop depth for dive profiles.
Sets up to five gas mixes for open circuit and rebreather bailout diving, marking gas types.
Sets oxygen/helium percentages for gases and defines operational depths for deco gases.
Configures diluent gases for CCR/PSCR diving, assigning types like First, Normal, or Disabled.
Sets up to five fixed setpoints for decompression calculation and their corresponding change depths.
Configures PSCR-specific settings like O2 drop per breath and lung ratio for calculation.
Explains how the OSTC records dive data, stores it, and how memory management works.
Describes chronological sorting, entry details, and accessing dive profile information.
Sets interval, bottom time, and maximum depth to calculate decompression stops for planned dives.
Initiates a dive simulation, allowing dynamic changes to depth and dive time within the simulation.
Lists essential dive data consistently displayed, such as depth, divetime, NDL/TTS, and current gas.
Details optional information displayable in dive mode, including stopwatch, decoplan, and tissue saturation.
Explains how warnings (red/yellow) indicate critical conditions like low battery, high ppO2, or fast ascent.
Enables gas changes during a dive, selecting prepared mixes, and handling lost or new gases.
Allows switching between configured setpoints while diving in CCR mode.
Facilitates switching to bailout gases (open circuit) or configuring new/lost gases and diluents.
Displays ascent rate warnings and manages dive logging for consecutive dives within a short interval.
Outlines cleaning instructions for the OSTC housing and care for the bungee wristband.
Details the wireless inductive charging method, pad indicators, and optimal charging status.
Provides instructions for replacing the battery in OSTC Plus models and mentions battery types.
Explains connecting the OSTC via Bluetooth to a computer or smartphone for software and logbook transfer.
Recommends using the latest stable firmware for optimal OSTC performance, available on the website.
Details display resolution, field of view, and Bluetooth connectivity standards.
Lists sensor types (depth, temp, compass) and power supply options (Lithium Battery, AA).
Describes housing materials, device dimensions for different models, and weight.
Instructs on proper disposal of electronic devices according to the WEEE directive for environmental protection.
