2.2.3. - Alarm clock (daily) and time signal setting.
The multifunction computer is equipped with alarm
clock and time signal functions using the time format set for
the clock display. Such functions may be switched on and
set, by depressing button A ( ) in sequence until the
(AL) icon appears on the display. By depressing button C
( ) the alarm clock hours and minutes start fla-
shing (picture 3), and they may be varied by depressing but-
ton D ( ). Depress button C ( ), in order to
confirm and switch on the set alarm clock time. Further
depress button C ( ) in order to switch on the time
signal (the icon “ ” will appear) and switch off the alarm
clock - the latter may be switched on again by further
depressing button C ( ) (both icons “ ” will
appear on the display). To switch off both functions depress
button C ( ): the related icons will disappear, and
the functions will be switched off.
The alarm clock rings for 20 seconds, and the related icon fla-
shes; just depress any button to switch off the alarm. The alarm
will stop ringing, but it will remain set on the chosen time.
If DIVE program is on, the alarm rings for 2 seconds.

2.3. - On surface, before diving.
As previously noted, the computer is always on and ready for
use. Although, it must always be checked that the appropria-
te altitude adjustments have occurred. The function is carried
out automatically, updating every 10 minutes the atmosphe-
ric pressure values and showing the related altitudes levels as
follows:
no icon ( ) - from 0 - 2.625 ft. (picture 1)
-
from 2.625 - 5.250 ft. (picture 1-a)
- from 5.250 - 7.874 ft. (picture 1-b)
- from 7.874 - 19.685 ft. (picture 1-c)
- more than 19.685 ft - out of range
Each icon indicates that the computer has automatically modi-
fied its own mathematical model to adjust to proper altitude.
 DANGER: Diving at altitudes greater than 9.842 ft.
above sea level involves an increase risk of decompres-
sion sickness.
It should be noted that at higher altitudes the nitrogen balan-
ce between the human body and the environment is altered.
It is therefore recommended to wait some hours after arriving
before diving, in order to allow a partial release of the excess
nitrogen from your body. The atmospheric pressure at higher
altitudes is in fact lower than at sea level: the diver has addi-
tional nitrogen in his body than at the lower altitudes. The
excess is gradually released and the balance re-established
within a couple of days.
At this point, it is important to check:
the low battery indicator should not be on or flashing (picture
4 a-b);
the computer is operating, displaying all liquid crystal segments.
