Cisco 8832 User Manual page 17

The conference phone supports an optional kit with two wired expansion microphones. You can extend the
microphones up to 7 feet (2.13m) from the phone. For best results, we recommend that the microphones be
placed at least 3 feet (0.91m) away from the phone.
Plug the end of the microphone cable into the port on the side of the conference phone.
Extend the microphone cable to the desired position.
The following figure shows installation of a wired expansion microphone.

When the conference phone is in a call, the LED on the expansion microphone is lit green. To mute the
expansion microphone, press the Mute key. When the microphone is muted, the LED is lit red. When the
battery in the microphone is low, the LED blinks rapidly.
