To avoid feedback, position the desk microphone and the external speaker as far away from each other as possible.

Desk Microphone

The desk microphone replaces the microphone that is integrated in the telephone and assists in optimizing the "speakerphone" function in poor acoustic conditions.

If the external speaker button on the telephone is pressed, an LED lights up on the microphone to show that the microphone is now ready to record.

The microphone can be switched off by pressing the mute key. Deactivation is confirmed when the LED goes out.

optiset E External Speaker

The active external speaker enhances the speaker already integrated in the telephone and im- proves the acoustic features and is therefore most suitable for telephone conferences.

When the external speaker is connected to the power network, an LED lights up to show that is operational. The external speaker button on the telephone activates this function.

The base volume can be adjusted in line with the given room conditions using the automatic volume control key on the front of the telephone. Volume control during a call is controlled via the volume key on the telephone.
