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.

You can end a PTT broadcast by releasing the Talk soft key, or by pressing 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.

You can adjust the volume of PTT broadcasts while they play. During a 

broadcast, press 

 to adjust 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, 

only system administrators can adjust the volume level of an Emergency 

broadcast.

While you send a broadcast, you can press 

 to mute your audio so that 

the people receiving your broadcast won’t hear anything. This behavior is 

similar to a phone call.

If you press and hold the Talk soft key, your broadcast will automatically 

transmit on the default channel, Channel 1. If you want, you can change the 

default channel.
