Pre-dive screen
The pre-dive screen is the same for all dive modes, but each mode has several dive mode specific options that can be adjusted to your diving needs.
A set of icons appears on the pre-dive screen, depending on what you are using with the dive mode, such as heart rate, Tank POD and GPS. The following elements can be seen on the display:

Tank POD icon if linked and active
GPS signal if enabled
If heart rate belt is enabled
Remaining battery time in hours
Active gas mix
Tank pressure if linked to Tank POD and active
The set maximum partial pressure limit (ppO2) for the active gas
The maximum operating depth (MOD) for the active gas
Active dive mode
GPS signal: The arrow icon (connected GPS) flashes gray while searching and turns green once a signal is found. We recommend to wait for the GPS icon to turn green before jumping into the water for accurate GPS location.
Heart rate: The heart attached to a belt icon (heart rate) flashes gray while searching and once a signal is found, it turns green. See Pairing Tank PODs and sensors for pairing a heart rate sensor.
Tank POD: The tank icon on the left is only visible if you have a Tank POD paired to your gas and it is active.
Battery: The battery icon tells you how many hours you can dive before the battery runs out.
