Installation and Setup
To ensure proper setup and best performance, it is strongly recommended that you complete the first time installation and setup at a dive shop. You should fully test the transceiver installation above and below water before using it during a dive.
Transceiver Position Tips
The transceiver communicates wirelessly with your compatible watch. On the surface, it uses ANT® technology. Underwater, it uses the SubWave™ sonar network. Your body, drysuit, and dive equipment can obstruct the signal, particularly while underwater. For the best reception, all transceivers in your group should have clear lines of sight to the watch. To help prevent blocking the signal with your body or equipment, you should follow these tips.
-
You should install the transceiver on the same side of the tank as the wrist wearing your watch. For example, if you wear your watch on your left wrist, you should install the transceiver on the left side of the tank regulator.
-
For the best reception, you should wear the tank high on your back. This allows the transceiver to have a clear line of sight over your shoulders.
-
You should install the transceiver at least 7 cm (3 in.) from your body.
-
If you wear your tank inverted with the regulator at the bottom, you can use a high-pressure hose to relocate the transceiver to have a clear line of sight over your shoulders.
-
If you lose the signal from your transceiver, you should move your arm until the signal is restored.
-
If you lose the signal from another diver, you should change your body position until the signal is restored. If your body is between the transceiver and another diver, it may obstruct the signal from that diver's transceiver.
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.
Installing the Transceiver on a High Pressure Hose Extension
Always use the pre-installed flow restrictor when using the transceiver directly attached to your regulator (Installing the Transceiver on Your Tank Regulator). Always use the included air spool when connecting the transceiver to 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 a high pressure hose extension certified to the EN 250:2014 standard, you should read the transceiver position tips and choose a position that provides the best line of sight to the watch (Transceiver Position Tips).
To install the transceiver, you need an open-ended wrench and a small flat screwdriver or flat-nose pliers.
-
Use a screwdriver or pliers to carefully remove the flow restrictor from the transceiver.
Use care when removing the flow restrictor to avoid damaging the device.
-
Insert the large end of the air spool into the transceiver.
-
Detach the first-stage regulator from the scuba cylinder and second-stage regulator.
-
Screw the transceiver onto the high pressure hose extension until you feel resistance.
Verify the installed transceiver does not physically interfere with any hoses or other tank assemblies.
-
Use an open-ended wrench to tighten the transceiver until it is secure.
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.
You must remove the air spool and reinstall the flow restrictor before installing the transceiver on your tank regulator.
