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.

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.

L3 Ô Press the L3 line key on your extension.

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