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 signals can be switched off if desired (see page 46). The actual attenti-
on message displays are not affected by the acoustic signal 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 frac-
tion below 19% O
2
(Oxy2 only).
– The calculation of Remaining Bottom Time (RBT) assumes a certain remaining tank pressure at the
surface (see page 65). This remaining pressure can be adjusted from 30 to 100 bar.
– 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.
– 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 physiological O
2
-consumption supported by the SCR can be adjusted.
– The sensitivity of the workload warning can be adjusted.
ppO
2
max must not be set higher than 1.6 bar
If you switch off the acoustic attention buzzer of the Aladin
®
Air Z O
2
you must
pay careful attention to the visual signals on the face of the Aladin
®
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.
