User`s guide

The above settings take place as follows:
• Blinking units digit; use the <-> button to enter the desired value.
• Blinking tens digit; use the <-> button to enter the desired value.
• Blinking hundreds digit; use the <-> button to enter the desired value.
• Blinking thousands digit (psi); use the <-> button to enter the desired value.
100 BAR ALARM (1450 PSI) SETUP
On entering this setup, the yellow warning light will start to blink.
This is an on/off type setting and can be used to disable the yellow 100 bar
warning light.
If the warning is disabled, the corresponding visual indication will not appear
during the dive. If the 100 bar warning has been disabled, pressing the
<MODE> button will enter the setup of the 50 bar low-air limit, otherwise it
will enter the setup of the 100 bar low-air limit. The on/off setting can be
toggled using the <-> button.
SETUP OF THE 100 BAR (1450 PSI) LOW-AIR LIMIT
The default value for this limit is 100 bar (1450 psi). This function can be
used to change the limit, using the <-> button, in the range from 80 bar
(1160 psi) to 120 bar (1740 psi), in increments of 10 bar (145 psi).
SETUP OF THE THE 50 BAR LOW-AIR LIMIT
On entering this setup, the red warning light will start to blink .
The default value for this limit is 50 bar (725 psi). This function can be used
to change the limit, using the <-> button, in the range from 50 bar (725 psi)
to 70 bar (1015 psi) in increments of 10 bar (145 psi).
SET5 - DATE AND TIME SETUP
To enter SET5, press <Mode> for approximately 2 sec.
To skip to SET6 press and immediately release the <Mode> button.
To go back to SET4, press and immediately release the <-> button.
The display shows the current date and time, with the date digits blinking.
The blinking value can be incremented by pressing <-> (hold down the
button for rapid increment); when the desired value is reached, press
<Mode> to save the new setting and go on to the next value (month). After
setting the minutes, AIRLAB checks the compatibility of the date and month
settings, taking leap years into account. If the date and month are
incompatible with each other, pressing the <Mode> button returns to the
date setting instead of advancing to SET6, prompting the user to correct the
date. In this way it is not possible to enter inexistent dates such as April 31
or February 29 2001.
SET6 - CLEAR RESIDUAL NITROGEN
MEMORY
This set function is used for clearing the residual nitrogen memory.
The display initially shows the "desat" icon.
To enter SET6, press the <Mode> button for approximately 2 sec (fig. 5).
Alternatively, to exit SET mode and advance to CLOCK mode, press and
immediately release the <Mode> button.
To go back to SET5 press and immediately release the <-> button.
To clear the residual nitrogen memory, press and hold down the <-> button
for at least 6 seconds. The clearing of the nitrogen memory is confirmed as
shown in fig. 6.
ACTIVATING DIVE MODE
DIVE mode is activated by means of the buttons. When the <Mode> button
is pressed in OFF mode, the AIRLAB performs the autozero procedure (depth
calibration) and the low battery check. Then it illuminates the display and
backlight for approximately 2 seconds and, if everything is working correctly,
the instrument goes into PreDive mode.
If a dive is started without switching on the computer, AIRLAB will
nevertheless activate automatically, thanks to its continual monitoring of
ambient pressure and tank air pressure, within 30 seconds of exceeding the
depth of 1.5 meters.
In this case, the computer does not perform the autozero depth calibration,
but uses the most recent data (last ambient pressure reading, which takes
place every 30 sec), after which it measures the tank air pressure and goes
into [DIVE] mode.
AIRLAB monitors the tank air pressure in the following way:
• [OFF] mode - every 30 sec. Detects opening of the air valve, switches on
and goes into [DIVE] mode
• dive mode (pre dive) - at 20 sec intervals
• dive mode (when the depth is greater than 1.5 meters) - at one minute
intervals.
AIR DIVE
The various operating phases of DIVE mode are described below:

WARNING
This option is intended only for highly experienced divers. Users who
clear the residual nitrogen memory cannot then use the instrument for
repetitive dives. After this operation, do not dive with AIRLAB if you
have already dived within the previous 24 hours.

WARNING
Correctly entering the tank volume is of fundamental importance in
order to obtain an exact indication of air consumption and residual
air time.

WARNING
In this case it is necessary to enter the theoretical value of pressure
(in psi) corresponding to the rated tank capacity in cu. ft. Do not
use the actual pressure measured by the instrument. Example: 80
cu.ft. tank at 3000 psi. Even if the tank is filled to a pressure
different from 3000 psi, enter 3000 psi on the AIRLAB.
