displayed.

select that menu parameter and press the PTT switch

PHONE option switch or F1 (Exit) key.

The Call Alert™ feature allows pages to be sent 

and received. With SMARTNET/SmartZone opera-
tion, either the Enhanced Private Conversation™ or 
Standard Private Conversation mode may be

system. With P25 Trunked operation, operation is 
similar to the enhanced mode.

If the radio being called is on the air, ringing is

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

uous tone is heard instead of ringing and “NO 
ACK” is displayed.

not answer, you will simply not hear a response.
