System and operation
2.6 Active backlight
The display of XP AIR can be illuminated both on the surface and
underwater.
The backlight can be activated by pressing on top of the case. The light
will turn off automatically after 8 seconds or after the time selected via
Dive.Log.
The backlight can only be activated if the computer display is on.
2.7 Switching off the display
On the surface XP AIR switches off automatically after 3 minutes without operation.
3 sOs mode
Activation: automatic
If the diver remains above a depth of 0.8m (3 feet) for more than three
minutes without observing a prescribed decompression, the computer will
automatically switch into SOS mode after the dive.
The display shows the "SOS" sign and the remaining length of the SOS
mode. The dive will be entered in the logbook with "SOS". Other than that
the SOS mode has no further impact on the displays and functions on the
surface.
• Serious injury or death may result if a diver does not seek immediate treatment should any signs or
symptoms of decompression sickness occur after a dive.
• Do not dive to treat symptoms of decompression sickness!
• Diving in SOS mode is extremely dangerous and you must assume full responsibility for such
behaviour. SUBGEAR will assume no liability.
Once in the SOS mode, the computer will lock up and will be inoperable as a diving instrument for 24
hours.
A diving accident can be analyzed at any time in the logbook and downloaded to a PC by means of
the infrared interface (IrDA) and the Dive.Log software.
