Transmitter Settings
You can customize the settings for paired transmitters prior to a dive.
On the paired Descent dive computer, hold MENU, select Dive Setup > Air Integration > Transmitters, and select
a transmitter.
Status: Enables a connection to the transmitter, and shows current connection status.
Identify: Plays a tone on the selected paired transmitter. This helps you to identify the transmitter without
needing to look at the transmitter ID printed on the transmitter housing.
Units: Sets the pressure units for your tank. The device defaults to psi if your depth setting is in feet, and bar if
your depth setting is in meters.
Working Pressure: Sets how much pressure the tank has when full. This value is used to determine the upper
end of the pressure gauge, and to calculate respiratory minute volume (RMV) for tanks using psi units.
Reserve Pressure: Sets the threshold values for reserve pressure and critical pressure alerts to appear on the
dive computer.
Volume: Allows you to enter the air volume of the tank. You can use the Reset Volume option if you move the
transmitter to a different size tank.
NOTE: This value is required to calculate volumetric surface air consumption (SAC) and respiratory minute
volume (RMV) (Selecting the Gas Consumption Rate Metric, page 19).
SAC/RMV/ATR: Enables the transmitter to be included in volumetric surface air consumption (SAC), respiratory
minute volume (RMV), and air time remaining (ATR) estimates (Including Transmitters in Gas Consumption
Calculations, page 19).
Set Transmit Power: Allows you to adjust the power setting if your transmitter is losing connection with the
paired dive computer underwater.
About: Displays the transmitter ID, software version, and battery status.
Name: Allows you to enter an easily identifiable name for the transmitter.
Remove: Allows you to remove a paired transmitter.
Selecting the Gas Consumption Rate Metric
1 Hold MENU.
2 Select Dive Setup > Air Integration > Display Setup > Gas Consumption Rate.
3 Select an option.
NOTE: The dive computer can estimate volumetric surface air consumption (SAC) or respiratory minute
volume (RMV) only if the air volume of the tank is entered in the dive computer (Transmitter Settings,
page 19). The dive computer can estimate pressure-based surface air consumption (PSAC) with or without
the air volume of the tank.
Including Transmitters in Gas Consumption Calculations
Gas consumption and air time remaining estimates are calculated using the tank pressure from the included
transmitters. By default, the first transmitter that you pair with your compatible dive computer is included. You
can include additional paired transmitters in gas consumption calculations.
1 Hold MENU.
2 Select Dive Setup > Air Integration > Transmitters.
3 Select a paired transmitter.
4 Select the SAC/RMV/ATR toggle switch to include the transmitter in gas consumption calculations.
5 If necessary, repeat steps 2 through 4 to include additional paired transmitters in gas consumption
calculations.
