Viking Portable 600 Radio Operating Manual

3 When the call is finished, end it as in the preceding Step 6.

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:

1 When a page is received, five beeps sound and “Page Rcvd” is displayed. The ID of 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 (see Section O), 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 or 

for 20 seconds, whichever occurs first. If no answer occurs within 20 seconds, a 
continuous tone sounds and “No Answer” is displayed.

- If the radio being called is not on the air, a continuous tone is heard instead of ringing 

and “No Ack” is displayed.

4 When the call is finished or if it could not be completed for some reason, end it by 

pressing the Unit Call option button or the <F1> (Exit) 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.

2 If required, press the Up/Down buttons to display the desired radio. The alias of each 

number is displayed.

3 Press the PTT switch or the <F2> button and one of the following occur:

- If five beeps sound, the system received the page and the paged radio is on the air and 

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.
