Using the Advanced Features of Your Phone

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 Updating Channel Subscriptions 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 on page 63).

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.
