A1 USER MANUAL
4.4.16 Low battery alarm
During the dive A1 will alert you if the
battery level is getting critically low. This
means you need to start the procedure to
terminate the dive, as there is not enough
energy in the battery to ensure the proper
functions and the computer may fail. Some
functions like backlight and audible alarms
are no longer available.
WARNING
Do not start a dive if the battery symbol is
blinking on the watch mode. The computer
may fail to function during the dive and this
could lead to serious injury or fatal issue.
4.5 No-Dive warning
If the A1 detects a situation of increased risk
(due to potential microbubble accumulation
from previous dives or a CNS O
2
level above
40%), the NO DIVE symbol will appear to
advise you against performing another dive
right away. The suggested time interval
that you should wait prior to diving again
is shown in the top left section of the dive
mode display.
You should not undertake a dive as long
as the no-dive warning is displayed on
the computer screen. If the warning is
prompted by microbubble accumulation
(as opposed to CNS O
2
over 40%) and
you dive anyway, you will have shorter no-
stop times or longer decompression times.
Moreover, the duration of the microbubble
warning at the end of the dive can increase
considerably.
4.6 No-Fly time
The no-y time is the time during which
an exposure to the reduced pressure
(equal to ascending at higher altitudes)
inside the cabin of an airplane could cause
decompression sickness, as calculated by
the decompression model in the computer.
The no-y symbol with countdown timer is
shown in the top right section of the display
until the restriction is completed.
