You’ll receive broadcasts on the channels you’re subscribed to as well as 
Channel 24 (the Priority channel) and Channel 25 (the Emergency channel). If 
you’ve enabled Do Not Disturb on your phone, you’ll only receive Emergency 
broadcasts. Non-emergency broadcasts won’t display or play on your phone.
When a broadcast ends, your phone emits an ‘end of transmission’ beep and 
enters a 10 second waiting period. During this period, you can respond to the 
broadcast (see Replying to PTT Broadcasts on page 4-18).
Receiving PTT Broadcasts When You’re Not in an Active Call
If you receive a broadcast and you’re not in an active call, the broadcast 
displays in the center of your screen and immediately plays, regardless of the 
broadcast priority.
Receiving PTT Broadcasts During Active Calls
How you handle a broadcast when you’re in an active call depends on the 
broadcast priority and if you’re allowed to receive a broadcast when you’re in 
an active call.
If the broadcast isn’t a Priority or Emergency page:
• If your phone is allowed to receive broadcasts during active calls, the 
broadcast displays in the inactive call group as an active broadcast (as 
shown next) and immediately plays. You’ll hear both the original call and 
the broadcast. To listen to only the broadcast, hold or end the call.
• If your phone isn’t allowed to receive broadcasts during active calls, the 
broadcast displays as a Pending broadcast. To listen to the broadcast, hold 
or end the call, or select the broadcast, and press the Accept soft key.
If it’s a Priority or Emergency broadcast, the broadcast displays in the inactive 
call group as an active broadcast and immediately plays. You’ll hear both the 
original call and the broadcast. To listen to only the broadcast, hold or end the 
call.
Replying to PTT Broadcasts
When a broadcast ends, you have a chance to respond to it before the channel 
closes.
When a broadcast ends, the broadcast enters a 10 second waiting period 
(as shown next). During this period, the channel remains open to receive or 
send additional broadcasts.
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.
