Receiving PTT Broadcasts
To receive a broadcast sent on a particular channel, you need to be subscribed
to that channel. To subscribe to a channel, see
on page 65.
How you receive a PTT broadcast depends on the broadcast priority, whether
you're in an active call, or if you're allowed to receive broadcasts during active
calls.
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
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 in the inactive call group as a held broadcast, as shown
next. To listen to the broadcast, hold or end the call or 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.
