Dive Warnings; Waking The Transceiver From Low Power Mode - Garmin DESCENT 12 Owner's Manual

Dive Warnings

• This device is for use by certified divers only.
• This device should not be used as the only source of pressure information. Always use backup instruments,
including a depth gauge, submersible pressure gauge, and timer or watch.
• Make sure that you fully understand the use, displays, and limitations of your device. If you have questions
about this manual or the device, always resolve any discrepancies or confusion before diving with the device.
Always remember that you are responsible for your own safety.
• The dive computer can calculate your surface air consumption rate (SAC) and air time remaining (ATR).
These calculations are an estimate and should not be relied on as the only source of information.
• Perform pre-dive safety checks, such as checking proper device function and settings, display function,
battery level, tank pressure, and bubble checks to check hoses for leaks.
• If a tank pressure warning or battery warning appears on the dive computer, terminate the dive immediately
and safely return to the surface. Disregarding the alarm may result in serious injury or death.
• For safety reasons, you should never dive alone. Dive with a designated buddy. You should also stay with
others for an extended time after a dive, because the potential onset of decompression illness (DCI) may be
delayed or triggered by surface activities.
• This device is not intended for commercial or professional dive activities. It is for recreational purposes only.
Commercial or professional dive activities can expose the user to extreme depths or conditions that increase
the risk of DCI.
• The transceiver is not an oxygen cleaned product. Do not use the transceiver with anything greater than 40%
oxygen.
