Your Extension’s Accessories

Connecting a Headset

A headset is connected with a cord inserted into the RJ12 female

connector labelled HEADSET located on the underside of your

extension.

This cord may be installed so that it comes out of either the left or

right side of your extension, as illustrated below.

When it is necessary to disconnect a headset cord, it is recom-

mended that you use a screwdriver to depress the release tab on

the RJ12 male connector.

Validating a Headset Connection

Once a headset is connected to your extension, you need to

validate that it is indeed properly connected. To do so:

í + * + 1 z Simultaneously press and hold the C, * and 1 keys on your

extension’s keypad for 1 second.

Your extension’s L3 line key should light. If this is not the case:

L3 Ô Press the L3 line key on your extension.

# z Next, press the # key.

This will then validate that the headset is indeed properly connected.
