Select your microphone and speakers by arrowing to the system you're using
and pressing on the remote control.
For most speakerphone systems, both the mic and speaker volumes should be
set to about 60% to start. Then adjust the volume for each by scrolling to that
control and pressing left or right on the arrows on the remote control.
Press the button on the remote control or scroll over to the Save button and
press on the remote control to Save the settings.
