System and operation
2.3 Switching on the display
• automatically, on submerging in water or when
adaptation to atmospheric pressure is necessary;
• manually, by bridging contacts on housing (B-E).
• When XP AIR is in state of rest no information
is displayed but the atmospheric pressure is
continuously monitored. If a higher altitude range
is detected, XP AIR switches on for 3 minutes
automatically -> 26.
XP AIR switches on by bridging the contacts B and E.
All segments light up for 5 seconds.
Afterwards the display shows the selected O
2
mix, the
temperature and in certain circumstances an altitude
range ->26.
If the transmitter is switched on and located within
transmitting distance, the tank pressure is displayed,
otherwise "---" will be displayed. If no transmitter has
been paired yet, the display will be blank.
If there is a remaining saturation due to the last dive or
change of altitude, XP Air also displays the remaining
desaturation time, the oxygen toxicity and the "no-fly
time" ->25.
2.4 Checking the battery capacity
After switching on XP AIR you can check the battery capacity by bridging
the contacts B and E. The remaining capacity is displayed for 3 seconds as
a percentage. If the value reaches 0%, the battery warning gets activated
(->17) and the battery has to be replaced by an authorised SUBGEAR
dealer.
For a 7-day diving vacation XP AIR uses between 2 – 5 % of its battery
capacity.
2.5 Selection and activation of user functions
At the surface you can select the dive planner, the logbook
and gauge mode as well as the functions to enter the O
2
%
mix and the microbubble levels by bridging the contacts
+ and B or – and B.
After the selection of the desired function you can activate and deactivate it by bridging the
contacts B and E.
