Manual Operation (Analog Multiline
Telephones Only)
Manual operation is appropriate when a headset is used occasionally. You
pick up the handset to answer a call and replace it to hang up. The headset
consists of the headpiece, and a modular base unit. The headpiece plugs into
the modular base unit, and the modular base unit connects to the telephone
through the HANDSET jack on the side of the telephone. The telephone
handset is plugged into the modular base unit. The modular base unit allows
you to adjust the incoming volume, switch between the headset and handset
as needed, and temporarily mute the line. (See Figure 3–21.)

multiline telephones, use a headpiece with a plug prong base unit and an

turn connects to the adapter. The adapter plugs into the OTHER jack on the
underside of the telephone, The plug prong unit provides switchhook control for
answering calls by pressing a button. You can also adjust the incoming
volume. On MLX telephones, the headpiece is attached to a modular base unit,
