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 on page 3-29
.)
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 attached to the
telephone. The handset is also attached to the modular base unit. (See
Figure 3-21 on page 3-29
