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 13.
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.
