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.
