COMPATIBILITY WITH YOUR TELEPHONE
It is very important that the Configuration Dial is positioned correctly. Audio problems
may be experienced if this is incorrectly set. If you cannot hear a dial tone through
your headset, turn the configuration dial until you obtain it. Then dial a co-worker and
while speaking, turn the configuration dial through the 4 positions. Select the position
that provides the best sound quality for both you and your co-worker. During this call
you should also adjust the Listen and Speak Volume as described next. Once set, the
configuration dial will not require any further adjustment.
