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.
