Installing the Transceiver on Your Tank Regulator
Always use the pre-installed flow restrictor when using the transceiver directly attached to your regulator. Always use the included air spool when connecting the transceiver to a high pressure hose extension (Installing the Transceiver on a High Pressure Hose Extension). Using the transceiver without either the flow restrictor or air spool could result in serious injury or death from an air pressurization failure.
Before you install the transceiver on your tank regulator, you should read the transceiver position tips and choose the port position that provides the best line of sight to the watch (Transceiver Position Tips).
-
Detach the first-stage regulator from the scuba cylinder and second-stage regulator.
-
Confirm the flow restrictor is installed in the transceiver, and screw it into the high-pressure output port until it is secure.
Verify the installed transceiver does not physically interfere with any hoses or other tank assemblies.
To prevent damage to the transceiver and possible loss of function, do not overtighten. Do not grip the regulator or the transceiver to move, carry, or adjust the tank.
