Gauge mode

In gauge mode All audible and visual alarms and attention messages are turned off. This
includes ascent speed, low tank pressure and interrupted signal from transmitter.
In gauge mode XP AIR will display depth, dive time and tank pressure, the maximum depth is stored,
ascent rate and tank pressure are monitored. Gauge mode does not support the calculation of no-stop
time or the supervision of decompression. Supervision of ppO
off. XP AIR will display no information about RBT or microbubble development. The settings for gas
mixtures, MOD and microbubble level cannot be set and the dive planner cannot be selected.
• Dives in gauge mode are performed at your own risk!
• After diving in gauge mode you should wait for at least 48 hours before using a decompression
computer.

Example: You are at 1200 m (3937 ft) (altitude range 1) and you may ascend to
range 2 only (2650 m / 8694 feet). You may not rise to the altitude range 3 or 4.
In order to assure optimal decompression even at higher altitudes, the 3m
(10 ft) decompression stage is divided into a 4 m (13 ft) stage and a 2 m (7
ft) stage in altitude ranges 1, 2 and 3. The prescribed decompression stop
depths are, in sequence, 2m / 4m / 6m / 9m... (7 ft / 13 ft / 20 ft / 30 ft...).
If atmospheric pressure is below 620 mbar (8.99 psi) (altitude higher than
4100 m / 13450 ft above sea level), no decompression data is calculated
and displayed (automatic gauge mode). In addition RBT and the dive
planner are not available anymore. The oxygen toxicity and the tank
pressure are still indicated.

! WARNING
Gauge mode can be switched on and off at the surface, if no desaturation
time is being prescribed.
After diving in gauge mode, XP AIR can not be used as dive computer for
48 hours.
Procedure:
1. Bridge contacts B and + or B and – until the gauge symbol and "on" or
"off" are displayed.
2. Confirm with B and E that you wish to activate or deactivate the gauge
mode. The gauge symbol starts flashing.
3. By bridging contacts B and + or B and – the gauge mode is switched
on and off.
4. Confirm your settings with B and E.
Without confirmation the display will disappear after 3 minutes and your
entries will not be accepted.
