A1 USER MANUAL
4.4.2
MOD (ppO
2
) alarm
If you exceed the maximum partial pressure
of the selected gas, the following alarm is
shown: MOD + DEPTH. The alarm remains
active until you ascend to depth where
ppO
2
is within safe limits.
WARNING
The MOD should not be exceeded. Disregarding
the alarm can lead to oxygen poisoning.
Exceeding a ppO
2
of 1.6bar can lead to sudden
convulsions resulting in serious injury or fatal
issue.
4.4.3
Dive time warning
If you have enabled the dive time warning,
this will be shown when the selected time
is reached. Refer to chapter
3.2.4.1 Dive
time warning
for setting this warning.
4.4.4
Turning time
When dive time warning is activated the A1
will alert you when it’s time to turn around
and start ascending to the surface.
4.4.5
No-stop time = 2 minute
warning
If you wish to avoid unintentionally
performing a decompression dive, the A1
can activate a warning when the no-stop
time reaches 2 minutes. This applies to
both L0 no-stop and MB no-stop time (see
chapter:4.6 for more information on MB
level diving). It gives you the opportunity
to start ascending before incurring a
decompression stop or a level stop
obligation.
4.4.6
No-stop time warning
The A1 can activate a warning when
the first mandatory decompression stop
appears. This alerts you to the fact that a
direct ascent to the surface is no longer
possible.
4.4.7
CNS O
2
warning (over 75%)
The A1 tracks your oxygen uptake via the
CNS O
2
clock. If the calculated value of
CNS O
2
reaches 75%, the A1 will emit a
sequence of audible beeps for 12 seconds
and the following display will be shown.
