Adjusting the Picture and Sound

Adjusting the Picture Quality

For details on the adjustment steps, see the section “Adjusting the Picture Quality on the Display” on page 89.

Adjusting the Volume

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.

Note

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

Cutting Off the Sound Momentarily - Mic Off Function

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.

Cutting Off the Sound On Answering - Mic Off Function

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.

For details on the “Mic on Answer” setting, see the section “Answer Setup Menu” on page 25.

To send the sound to the remote party

Press the (Mic Off) button on the PCS-TL33 again, or click (On) on the display.

Synchronizing Audio and Video - Lip Sync Function

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”.

For details on the “Lip Sync” setting, see the section “Communication Mode Menu” on page 29.

Note

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.

Reducing Echo - Echo Canceller

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