Using a headset with your telephone

The built in standard 2.5 mm jack allows you to use a headset with this telephone.

Using Headset

The headset jack automatically detects the headset when it is plugged in. This will allow all handsfree functionality to be enabled through the headset.

You can mute a call when on the headset, see To Mute a headset call on page 10.

Note: When the headset mode is enabled, the handset must remain in the cradle.

Extension in use

When you lift the handset or press P, the 9120 telephone automatically selects the prime line. If your prime line is Line 2 and the peripheral device (e.g. fax machine) is using that line, the line is not selected and the message Extension in use appears on the Þrst line of the display and Press line key appears on the second line of the display. If you press G, you access Line 1 and can make a call. If you press F, you will access Line 2 and may interrupt the call to the peripheral.
