Muting the Microphone
You can mute the microphone if you do not want the far site to hear
conversations at your site.
To mute or unmute the microphone:
>> Press Mute on the keypad or press Mute on the remote control.
If a Polycom tabletop microphone array is connected to your system, you can
also mute the call by pressing on the microphone.
Using a Headset or Desktop Speakers
You can connect headphones, a headset, or desktop speakers to the connectors
on the side of the Polycom HDX 4000 series system monitor. The microphone
input provides audio for video conferencing only; it does not provide input for
other computer applications.
Points to note about muting the microphone:
• Muting the microphone does not mute audio coming from your computer.
• The microphone might automatically mute when the system is asleep or is
waiting for you to log in.
• Polycom microphones are not supported on Polycom HDX 4500 systems.
• The microphone might automatically mute when the system automatically
answers an incoming call.
If you connect headphones, a headset, or desktop speakers, use a cable that is
10 ft (3 m) or shorter.
