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.
