Define Gas
The define gas function allows
you to set up 5 gases in Closed
Circuit and 5 gases in Open
Circuit� You must be in Open
Circuit mode to edit open
circuit gases, and you must be
in Closed Circuit to edit closed
circuit diluents� For each gas,
you can select the percentage
of oxygen and helium in the
gas� The remainder is assumed
to be nitrogen�
Pushing the right (Define)
button presents the function
to define gas number 1�
The left (Next) button
increments to the next gas�
Press the right (Edit) button to
edit a gas�
The first option is to toggle
the gas on or off as indicated
by the underline� Use the left
(Change) button to toggle the
gas on�
Continuing along, the gas
contents are edited one digit
at a time� The underline shows
the digit being edited�
Each push of the left (Change)
button increments the digit
being edited� When the digit
reaches 9, it will roll over to 0�
Pushing the right button
(Next) will lock in the current
digit, and move on to the next
digit�
A helpful indicator of what is
being edited is included in the
center at the bottom�
Pushing the right (Save) button
on the last digit will finish
editing that gas, and bring
you back to the gas number�
You can continue to increment
through the gases pressing the
left (Next) button�
The “A” denotes the active gas� You cannot turn off
the active gas in the Define Gas menu� If you try, it will
generate an error� You can edit it, but cannot set both
the O2 and HE to 00�
Setting any gas to 00/00 will automatically turn it off�
The computer will display all 5 gas entries available to
allow you to enter new gases�

turned on before every dive, especially if you often
use your dive computer for both open and closed
circuit diving�
