Introduction

WARNING

See the Important Safety and Product Information guide in the product box for product warnings and other

important information.

Installation and Setup

CAUTION

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.

Introduction 1

• 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 watch and another diver, it may obstruct the signal from that diver's transceiver.

2 Installation and Setup

Installation and Setup 3

Installing the Transceiver on Your Tank Regulator

WARNING

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, page5). 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, page1).

1Detach the first-stage regulator from the scuba cylinder and second-stage regulator.

2Remove the port plug from the high-pressure output port.

3Confirm the flow restrictor is installed in the transceiver, and screw it into the high-pressure output port until

it is secure.

WARNING

Verify the installed transceiver does not physically interfere with any hoses or other tank assemblies.

NOTICE

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.

4 Installation and Setup

Installing the Transceiver on a High Pressure Hose Extension

WARNING

Always use the pre-installed flow restrictor when using the transceiver directly attached to your regulator

(Installing the Transceiver on Your Tank Regulator, page4). 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, page1).

To install the transceiver, you need anopen-ended wrench and a small flat screwdriver or flat-nose pliers.

1Use a screwdriver or pliers to carefully remove the flow restrictor from the transceiver.

NOTICE

Use care when removing the flow restrictor to avoid damaging the device.

2Insert the large end of the air spool into the transceiver.

Installation and Setup 5

3Detach the first-stage regulator from the scuba cylinder and second-stage regulator.
