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 no one 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 braodcast ends. After you tap 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 3-25 .
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.
Note
If you release the Talk soft key while you’re sending the broadcast, the broadcast
temporarily stops and enters a 10 second ‘Waiting’ period. 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 no one broadcasts during the waiting period, the channel closes and the
broadcast ends.
