The Aladin
®
Air Z O
2
is able to communicate with a personal computer. The connection is established
by contact sensors and the MemoMouse. The MemoMouse and the PC software DataTrak and DataTalk
is available as an option. For the Aladin
®
Air Z O
2
it is only allowed to use DataTalk version 2.0 or higher.
Communication with a personal computer (Windows
®
) has a number of advantages:
1.1 Personal programming of the dive computer (DataTalk)
Several parameters can be set individually by the user, e. g.:
– The physical units of water depth and tank pressure can be selected (metric/imperial).
– The attention message acoustic alarm can be switched off if desired (see page 46). The actual alarms
(see page 49-50) shown on the face of the Aladin
®
Air Z O
2
are not affected by the acoustic alarm being
switched off. The acoustic messages for alarms cannot be switched off. Alarm messages are: RBT below
zero minutes (pressure transmitter only), ignoring decompression stop, making too rapid an ascent,
exceeding CNS O
2
limit, oxygen fraction below 19% O
2
(Oxy2 only).
If you switch off the acoustic alarm of the Aladin
®
Air Z O
2
you must pay
careful attention to the visual attention messages and alarms on the face of
the Air Z O
2
. Failure to follow all alarms whether audible or not may lead to
serious injury or death due to decompression sickness, and/or drowning.
– The calculation of Remaining Bottom Time (RBT) assumes a certain rest of tank pressure at the sur-
face (see page 65). This rest pressure can be adjusted from 435 to 1450 psi.
– The sensitivity of the warning message “increased workload“ can be altered.
– The maximum allowable partial pressure of oxygen can be adjusted between 1.2 and 1.95 bar.
ppO
2
max must not be set higher than 1.6 bar
– The time to reset the <O
2
% MIX> – entered manually or automatically by the Oxy2 – to air (21% O
2
)
between 1 hour to „no reset“ (default).
– The the divers maximum expected physiological O
2
-consumption rate supported by the SCR can be
adjusted.
– The sensitivity of the workload warning can be adjusted.
