DCU & Transmitter Field Installation Manual

The DCU unit should be in an open area away from other

electrical appliances (e.g. personal computers, laptops) or any

metal objects.

Installing the DCU Unit

In order to install the DCU unit:

1. Plug the appropriate end of the power adapter cord into

the 12VDC socket at the back of the DCU unit.

2. Plug the power adapter into a wall power socket. The

DCU unit makes an audible beeping sound and then runs

through a series of built-in-tests to check that everything

is in order.

3. After completing the tests successfully the DCU unit

beeps again and the two external LED’s, located at the

rear of the DCU unit, are turned on. This indicates that the

DCU unit is in working order. The LED indicators are:

• Left LED - indicates that power is connected

• Right LED - indicates that the DCU unit has

registered to a telephone network (network

registration may take up to one minute after built-in-

test completion).
