ALADIN SQUARE USER MANUAL
Once PDIS depth has been reached,
you should stay on the zone that is
-0.5m..+3.0m / -2ft..+10ft from the shown
PDIS depth. If you descend below this zone
the PDIS counter will be deactivated and
Square calculates a new PDIS depth.
WARNING:
Even when performing a PDI stop, you still
MUST perform a safety stop at 5m/15ft for 3 to
5 minutes. Performing a 3 to 5 minute stop at
5m/15ft at the end of any dive is still the best
thing you can do for yourself!
2.8 Gauge mode
When Square is set to gauge mode, it will
only monitor depth, time, and temperature,
and will not carry out any decompression
calculations. You can only switch to
gauge mode if the computer is completely
desaturated. All audible and visual warnings
and alarms, other than the low battery
alarm, are turned off.
WARNING:
Dives in gauge mode are performed at your
own risk. After a dive in gauge mode you must
wait at least 48 hours before diving using a
decompression computer.
When on the surface in gauge mode,
Square will show neither the remaining
desaturation time nor the CNS O
2
% value.
It will however display a surface interval up
to 24 hours and a 48 hour no-fl y time. This
no-fl y time is also the time during which you
cannot switch back to computer mode.
The gauge mode surface display after a
dive shows the dive time at the bottom row
left. In the top row right the stopwatch is
running from the dive start or last manual
restart. On the bottom row right the
maximum depth of the dive is shown. After
5 minutes timeout the display changes to
gauge menu mode.
During a dive in gauge mode, Square
displays a dive time in the bottom row left.
The stop counter is shown at the top row
right and it can be reset and restarted by
pressing SEL button.
