The Call Alert™ feature allows pages to be sent and received on P25 conventional 
channels. The Call Alert Encode and Decode options must be enabled to send or receive 
an alert. Operation is similar to SmartNet/SmartZone and P25 Trunked channels.

To answer a page:

the radio paging you is stored as the last ID received.

2 To clear or ignore the page, press any option button. If the PTT switch is pressed, a 

group call is placed on the selected channel.

3 To answer the page as a unit call, press the Unit Call option button or select that menu 

parameter and the alias of the radio paging you is displayed. Press the PTT switch and 
respond. One of the following conditions then occur:

- If the radio being called is on the air, ringing is heard until the called party answers.

- If the radio being called is not on the air, “No Ack” is displayed.

4 When the call is finished, end it by pressing the Unit Call option button or the 

 

(Clear) button.

To initiate a page:

1 With a P25 conventional channel selected, momentarily press the Call Alert option 

button or select that menu parameter. The alias of the last ID called is displayed.

received it. The page mode is automatically exited.

- If the system received the page but the called radio is not on the air, a single beep 

sounds and “No Ack” is displayed after six attempts after the PTT switch is pressed.

If programmed, the Call History feature stores the IDs of the last five radios that have 
made talkgroup calls, unit calls, or call alerts to the user’s radio. To view the Call History 
list:
