Handsfree Operation
Your telephone is capable of both half-duplex and full-duplex handsfree
operation.
Both modes of operation allow you to conduct conversations without the use
of a handset or headset. Full-duplex operation allows you and another user
with full-duplex capability to converse without overriding each other's voices.
The other user may be using a handset, a headset, or they may be in
speakerphone mode.
Full-duplex operation requires that your telephone be connected to an
external power adapter. For some environments (e.g. noisy locations), full-
duplex handsfree operation may not be suitable. To return to full-time, half-
duplex mode, disconnect the external power adapter.
For best performance, users should note the following:
z
After a conversation begins, your telephone may take several seconds to
determine ideal speaker and microphone levels before commencing full-
duplex operation. During this time, your telephone will operate in half-
duplex mode.
z
While in speakerphone mode, your set may temporarily shift to half-
duplex mode if room conditions change (i.e. other persons enter the room)
or your hand passes in front of the microphone.
z
Your speakerphone works best in a quiet, echo-free environment. (NOTE:
Excessive background noise originating with other connected parties can
impair communication using the speakerphone. If the noise persists,
continue the call using the handset or switch to half-duplex operation by
disconnecting the power adapter.)
z
Do not place your set near sources of noise such as PC fans, etc.
z
You should face your telephone when you speak and you should be no
more than four to six feet away. Take care not to block the microphone
with papers or other objects.
To use Handsfree Operation to make calls:
1. If you want to use a Non-Prime Line, press a Line Appearance key.
2. Dial the number.
3. Communicate by using the speaker and the microphone.
