Press 

© to switch off the telephone microphone so that you can speak to a person in your 

office while you are on a handsfree call. The display reads 

Microphone Muted

.

Press the handsfree button to turn the microphone back on again and continue your handsfree 
call.

Press the handsfree button.

Hang up the handset. 

To switch from handsfree, lift the handset.

The indicator next to the handsfree button is solid when you have Handsfree turned on. It flashes 
when you mute the microphone.

Wait for your caller to finish speaking before you speak. The microphone and speaker cannot both 
be on at the same time. Your caller’s voice can be cut off if you both speak at the same time. 
Interruptions such as a tapping pencil can be loud enough to turn on your microphone and cut off 
your caller’s speech.

To prevent an echo, keep the area around your telephone free of paper and other objects that can 
screen your microphone. Turn down the microphone’s volume (press the left end of 

√ 

while speaking) to prevent feedback. When you change the volume level, both the microphone and 
speaker volume adjust to prevent feedback problems.

Position the telephone so that any unavoidable local noise (such as an air conditioner) is behind it. 
This position limits the amount of background noise.

You can program the type of Handsfree used with each telephone or activate Handsfree 
Answerback.

You need to start a Unified Manager session to program this feature. For more information about 
programming using Unified Manager, see the Business Communications Manager Programming 
Operations Guide.

In open office environments, use the handset when handsfree 

communication is not necessary or when you need privacy during a call. 
Another option is to use a headset.
