SPEAKERPHONE ADJUNCT
Description
The speakerphone adjunct permits users of voice terminals not equipped with built-in
speakerphones to place and receive calls without lifting their handsets. The adjunct has an
On/Off switch, a switch to temporarily mute the microphone, status lamps, and a volume
control (for incoming voice only).
All voice terminal features operate normally with the speakerphone adjunct.
Lifting the handset during speakerphone operation automatically turns off the speakerphone.
The speakerphone may be turned on during a call by pressing the On/Off switch and
hanging up the handset.
Considerations
Speakerphone operation allows users to perform other activities while carrying on a
conversation. Speakerphones also facilitate conference calls.
