5 When you finish your broadcast, do one of the following:
— Release the Talk soft key. The broadcast temporarily stops and enters 
a 10-second waiting period to allow others to reply, or you to resume 
the broadcast. If noone responds during a waiting period, the channel 
closes and the broadcast ends.
— Press the End PTT soft key. The broadcast temporarily stops and 
enters a 10-second waiting period to allow others to reply. If there are 
no replies, the channel closes and the broadcast ends. After you press 
the End PTT soft key, you can immediately initiate another broadcast 
on another channel, even if the previous broadcast is still in its waiting 
period.
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 95.
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 94).
If you release the Talk soft key while you’re sending the broadcast, the broadcast 
temporarily stops and enters a 10 second ‘Waiting’ period, as shown next. During 
this period, the channel remains open to give people a chance to reply. At any time 
during the waiting period, you can resume your broadcast by pressing and holding 
the Talk soft key. If noone broadcasts during the waiting period, the channel closes 
and the broadcast ends.
