Muting the Speakerphone
If you have a Mute key, you can press it to turn off the
microphone, so that you can carry on a conversation
in your room that the other party on your line cannot
hear.
Mute is also helpful when someone puts you on hold,
since it lets you hear your party reconnect even if
there is a high noise level in your room.
To mute the
speakerphone ➩ During your conversation, press the MUTE
key.
The status light next to the MUTE key blinks to
remind you that Mute is active.
To cancel ➩ Press the MUTE key or lift the handset.

active, someone nearby can hear your conversation,
but whatever they say will not be picked up by the
speakerphone.
