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
One-Touch Operation (All Telephones)
One-touch operation allows you to touch a button to answer a call. On analog
multiline telephones, use a headpiece with a plug prong base unit and an
adapter (502C). The headpiece connects to the plug prong base unit, which in
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, which is
