Creating a Group Call

If you hear a busy tone, release the button and wait a moment before making another attempt. Ensure that
PTT Express and the WLAN are enabled.
2. Start talking after hearing the talk tone.
NOTE: Holding the button for more than 60 seconds (default) drops the call, allowing others to make Group calls. Release
the button when finished talking to allow others to make calls.
Responding with a Private Response
The Private Response can only be initiated once a Group Call has been established. The initial Private
Response is made to the originator of the Group Call.

2. Within 10 seconds, double-press the PTT button, and listen for the talk tone.
