conference call had originated on the conference phone. If the PBX limit has not been reached, new parties may be added or dropped as described earlier. Caution: attempting to move conferences before the cycle is complete, i.e. before the call

is established, and included or dropped, will result in dropping all callers if you subsequently push the ON/OFF button on the conference phone.

Mute Initiated By the Meridian Phone

If you have a Meridian phone connected to the Interface Module, and your SoundStation Premier 500D/550D

is in use, you may use your phone to break away from the public conference call to speak privately to the far end(s) without disconnecting the conference call.

When you lift the handset, all microphones and the speaker on the console are muted. The red LED’s will blink to indicate

the mute condition. When the handset is returned to the cradle, the conference call is resumed and the LED’s return to a steady state.

Using Extended Microphones With 550D

Your SoundStation Premier 550D may be adaptable to a larger conference room with the addition of Extended Microphones.

If not purchased with your SoundStation Premier 550D, these are available as an accessory from your Polycom Distributor.

To mute all microphones from the extended microphone, press MUTE.

To resume two-way communications, press MUTE again. The red LED will return to green.

An ON/OFF switch is located on each of the extended microphones.

By switching to the O position, the LED MUTE light will turn red and only this microphone will be shut off. Switching to the 1 position will turn the microphone back on.
