8.2 Volume Control
If the volume from the far-end is either too faint or too loud, you can adjust it with 
the VOLUME
 buttons on the hand held remote.
8.2.1  Increase the volume
¬
Press the VOLUME
 UP
 button.
The volume bar appears on the monitor to show you the volume level.  We 
recommend that you do not use the volume control on your monitor to adjust the 
volume because this may interfere with your ability to adjust the volume with the 
hand held remote.  Also, if the volume of the monitor is too high or too low, the 
people at the far-end may hear echo.  In general, leave the monitor volume level 
set to about middle position.  If the far-end does hear echoes, turn the near-end 
monitor volume down until the echo disappears.
8.2.2  Decrease the volume
¬
Press the VOLUME

 button.
