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.
	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 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 3-15.
	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.
