Normal By default, broadcasts sent to Groups/Channels 1 to 23 are considered Normal
broadcasts. If two users begin a broadcast on the same group/channel at the same time, the
phone with the lower serial number will continue to transmit while the other phone will enter the
receiving state. By default, all phones are configured to receive broadcasts sent to
Group/Channel 1.
Priority By default, broadcasts sent to Group/Channel 24 are considered Priority broadcasts.
A Priority broadcast will interrupt Normal broadcasts or active calls. All phones receive Priority
broadcasts unless Do Not Disturb is enabled. Phones play Priority broadcasts at the phone’s
current audio level.
Emergency By default, broadcasts sent to Group/Channel 25 are considered Emergency
broadcasts. An Emergency broadcast will interrupt Normal broadcasts, Priority broadcasts, and
active calls and plays out at near maximum volume even if Do Not Disturb is turned on.
Push-to-Talk Mode
Your system administrator can enable your phone to operate in a broadcast mode called Push-
to-Talk (PTT). In order to send and receive PTT broadcasts, you have to subscribe to PTT
channels.
PTT broadcasts are collaborative: you can transmit messages and listen to replies.
Sending and Receiving PTT Broadcasts
By default, you’re subscribed to Channels 1, 24, and 25. This means that you can send and
receive PTT broadcasts on Channels 1, 24, and 25.
When you end a PTT broadcast, the channel remains open and enters a waiting period. This
waiting period gives people who received the broadcast a chance to respond. If no one
responds within the waiting period, the channel closes.
Sending PTT Broadcasts
Before you can send a PTT broadcast, you need to choose a channel to broadcast on. Or, you
can hold the Talk soft key to immediately begin broadcasting on Channel 1, the default channel.
You can change your default channel to any channel you want (see Updating the Default
Channel). When you change the default channel, you’re automatically subscribed to it.
To send a PTT broadcast:
