placed on hold. Phones play Priority broadcasts at the phone’s current audio level.

Emergency (for Group/Channel 25)—Broadcasts sent to Group/Channel 25 are considered Emergency broadcasts. All phones receive Emergency broadcasts (even if Do Not Disturb is enabled), and play them immediately. By default, phones play Emergency broadcasts at the highest audio level. The audio level will return to normal for subsequent non-Emergency broadcasts.

Push-to-Talk Mode

Your phone may be enabled to operate in a broadcast mode called Push-to-Talk (PTT). In PTT mode, you broadcast messages on a specific channel. In order to send and receive PTT broadcasts on certain channels, you have to subscribe to those channels.

PTT broadcasts are collaborative: you can transmit messages and listen to replies.

Sending and Receiving PTT Broadcasts

To send and receive PTT broadcasts, you need to subscribe to certain channels. By default, you’re subscribed to Channels 1, 24 (the Priority channel), and

25 (the Emergency channel). This means that:

You can send PTT broadcasts on Channels 1, 24, and 25.

You’ll receive PTT broadcasts sent 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

If you send a PTT broadcast without specifying a channel, it’s automatically transmitted on the default channel. Channel 1 is the default channel that all broadcasts transmit on, if no channel is specified for a broadcast.

You can change your default channel to any channel you want (see Updating the Default Channel on page 4-19). If you change your default channel, you’ll become subscribed to that channel automatically. To subscribe to a channel, see Updating Channel Subscriptions on page 4-20).
