Turning Off the Sound On Answering – Mic on Answer Function
You can turn off the sound to be sent to a remote party when you have
answered a call from the remote party.
If you set "Mic on Answer" to "Off" in the Answer Setup menu, only the
picture on the local party will be sent to the remote party when answering a
call. The "MIC OFF" indicator appears on the monitor screen.
For the Mic on Answer setting, see "Answer Setup Menu" on page 52.
To send the sound to the remote party
Press the MIC ON/OFF button on the Remote Commander.
Synchronizing Audio and Video – Lip Sync Function
During the conference a time lag may occur between the sound and picture to
be sent to the remote party.
When you set "Lip Sync" to "On" in the Audio Setup menu, the system adjusts
to synchronize audio and video. However, this may delay transmission of
audio synchronized with video.
For the Lip Sync setting, see "Audio Setup Menu" on page 56.
Note
To enable the Lip Sync function of the remote party, you have to ask them to do so.
Reducing Echo – Echo Canceller
The Communication Terminal is equipped with the Echo Canceler, allowing
the echo that occurs during audio transmission to be reduced.
Setting "Echo Canceller" to "On" in the Audio Setup menu activates the built-
in echo canceller.
When using an external echo canceler, set "Echo Canceler" to "Off".
For the "Echo Canceller" setting, see "Audio Setup Menu" on page 56.
