Cutting Off the Sound On Answering – Mic on Answer Function
You can cut 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 display.
For the "Mic on Answer" setting, see "Answer Setup Menu" on page 43.
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 47.
Note
To enable the Lip Sync function of the remote party, you have to ask them to do so.
Reducing Echo – Echo Canceler
The system is equipped with the Echo Canceler, allowing the echo that occurs
during audio transmission to be reduced.
Setting "Echo Canceler" to "Internal" in the Audio Setup menu activates the
built-in echo canceler.
For the "Echo Canceler" setting, see "Audio Setup Menu" on page 47.
