, the decompression stop duration and
decompression stop depth begin to flash and an audible alarm
goes off. Due to the formation of microbubbles, decompression can
increase massively if a decompression stop is ignored. When the
surface is reached during the decompression alarm, the arrow
, the
decompression stop duration and decompression stop depth continue
flashing, in order to point to the risk of a decompression accident. The
SOS mode is activated 3 minutes after the dive if corrective action is
not taken (->16).
If the total (cumulative) duration of the decompression alarm is longer
than one minute, it is entered in the logbook.
Descend to the prescribed decompression stop depth immediately!
Total time of ascent As soon as decompression stops are necessary XP-H shows the total
time of ascent. This includes the ascent time from the current depth to the
surface and all decompression stop obligations.
F
The total time of ascent is calculated on the basis of the prescribed
ascent rate. Total time of ascent can be subject to change if the
ascent rate is not ideal (100%).
Ascent time greater than 99 minutes is displayed as " – – ".
!
WARNING
On all dives with XP-H, make a safety stop for at least three minutes
at a depth of 5m (15ft).
4.10 Safety stop timer
The safety stop timer displays the time span a diver should spend at the
safety stop depth at the end of the dive. The timer is activated by the diver
and counts back from 3 minutes to zero. It can be restarted any number
of times.
The safety stop timer can be activated under the following conditions: depth
< 6.5m (21ft), no-stop display 99 minutes.
Activate the safety stop timer by pressing
. The timer begins to count
backwards and a bookmark will be created in the dive profile. If you press
again, the timer will start again from the full value.
The safety stop timer will switch off automatically if the depth exceeds 6.5m
(21ft) or the no-stop phase is shorter than 99 minutes.
