Polycom IP 450 manual Ending PTT Broadcasts

Polycom SoundPoint IP 450 User Guide

During a waiting period, you can press and hold the Talk soft key and talk to all the people listening on the channel. When you finish talking, release the Talk soft key. The broadcast will enter another waiting period until someone broadcasts again. If no activity occurs within the waiting period, the channel closes and no more broadcasts can take place.

Ending PTT Broadcasts

You can end a PTT broadcast by releasing the Talk soft key, or by tapping the End PTT soft key. After you end a broadcast, the channel remains open so others can respond.

If you release the Talk soft key without pressing the End PTT soft key:

•You can resume the broadcast by pressing and holding the Talk soft key (if the broadcast is in a wait period).

•You can’t initiate another broadcast on another channel until the waiting period ends.

If you press the End PTT soft key:

•You can’t resume the broadcast by pressing and holding the Talk soft key.

•You can immediately initiate another broadcast on another channel.

Adjusting the Volume of PTT Broadcasts

You can adjust the volume of PTT broadcasts while they play. During a broadcast, press either Volume Up or Volume Down to raise or lower the volume of the broadcast.

If you adjust the volume of a non-emergency broadcast, your phone retains the adjusted volume for all subsequent non-emergency broadcasts. However, even though you can adjust the volume of an Emergency broadcast, the adjusted volume won’t be retained for subsequent Emergency broadcasts. All Emergency broadcasts play at the same volume, until you adjust it.

Changing Where Broadcasts are Played

While you send a broadcast, you can pick up the handset or press the Speakerphone or the Headset key and continue speaking. You can also press the Microphone Mute key to mute your audio so that the people receiving your broadcast won’t hear anything. This behavior is similar to a phone call.

When you listen to a broadcast, you can pick up the handset or press Speakerphone or the Headset key and continue listening to the broadcast.

Updating the Default Channel

If you don’t select a channel to broadcast on, your broadcast will automatically transmit on the default channel, Channel 1. If you want, you can change the default channel.
