Technical Modes
Operating Instructions
Rated Pressure
Enter the rated pressure
of the tank on which the
transmitter is installed�
The valid range is 69 to 300 bar (1000 to 4350 psi)�
The only use of this setting is to scale the full-scale
range of the gas pressure bar graph that appears over
the numerical tank pressure number�
Reserve Pressure
Enter the reserve pressure�
The valid range is 28 to 137 bar (400 to 2000 psi)�
The reserve pressure setting is used for:
1� Low pressure warnings
2� Gas Time Remaining (GTR) calculations
A
“Reserve Pressure”
warning will be generated when
the tank pressure falls below this setting�
A
“Critical Pressure”
warning will be generated when
the tank pressure falls below the larger of 21 bar (300
psi) or half the reserve pressure�
For example, if reserve pressure is set to 48 bar, the
critical warning will occur at 24 bar (48/2)� If the
reserve pressure is set to 27 bar, the critical warning
will occur at 21 bar�
Rename
Allows the changing of the transmitters title as it
appears on menus and screens throughout the dive
computer� Two characters can be customized per
tank� The options are:
First Character: T,S,B,O, or D�
Second Character: 1,2,3, or 4�
Unpair
The unpair option is simply a shortcut to reset the
serial number to 000000�
When not using T1 or T2, for lowest power
consumption, disable receiving completely by setting
the AI Mode setting to Off�
GTR Mode
Gas Time Remaining (GTR)
is the time in minutes that
can be spent at the current
depth and SAC rate until a
direct ascent to the surface at
a rate of 10 m/min (33 feet/
min) would result in surfacing
with the reserve pressure� The
SAC rate is averaged over the
last two minutes of diving for
calculating GTR�
GTR and SAC are only based on one tank, or on
two tanks in sidemount configuration� Note that for
sidemount the tanks must be of identical volume for
SAC to be accurate�
The GTR/SAC setting is also used for identifying
sidemount mode� Selecting a SM option here will
enable tank switch notifications�
