You can adjust the volume of the sound to be heard during 
a videoconference.
Press the 

 (Volume) + button on the PCS-TL33 to 

increase the volume, and the 

 (Volume) – button to 

decrease it. 
You can adjust the volume separately for a 
videoconference and for computer display, and store the 
respective settings.

If increasing the volume results in acoustic feedback, 
decrease the volume setting.

You can momentarily cut off the sound to be sent to the 
remote party.
To do this, either press the   (Mic Off) button on the 
PCS-TL33, or click 

 (Off) on the display. The sound of 

the local system will not be heard by the remote party.

To restore the sound
Press the   (Mic Off) button on the PCS-TL33 again, or 
click 

 (On) on the display.

You can cut off the sound to be sent to a remote party when 
you have answered a call from the remote party.
To do this, set the “Mic on Answer” item in the Answer 
Setup menu to “Off”. Only the picture of the local system 
will be sent to the remote party when answering a call. 

To send the sound to the remote party
Press the   (Mic Off) button on the PCS-TL33 again, or 
click 

 (On) on the display.

During a videoconference, a time lag may occur between 
the sound and picture sent to the remote party.
When you activate the Lip Sync function, the system 
automatically adjusts the synchronization of audio and 
video. However, this may delay the overall transmission 
somewhat, because the audio will be delayed to match the 
video.
To activate the Lip Sync function, set the “Lip Sync” item 
in the Communication Mode Setup menu to “On”.

If there is an audio/video synchronization problem in the 
signal sent from the remote party, you have to ask the 
remote party to enable the Lip Sync function at their end.

The system is equipped with an Echo Canceller function 
designed to reduce the echo that can occur during 
bidirectional audio transmission.
