You can also make a Private Call via Contacts (see Making a 
Private Call from Contacts on page 45) or perform a quick 
alphanumeric search for the required alias via a keypad entry 
(see Making a Call by Alias Search on page 46).

up the call, it exits without any indication and returns to 
the previous screen.

Your radio may be programmed to perform a radio 
presence check prior to setting up the Private Call. If 
the target radio is not available, you hear a short tone 
and see negative mini notice on the display.

The radio returns to the menu prior to initiating the 
radio presence check.

respond to a Selective Call initiated by an authorized 
individual radio, your radio must be programmed for you 
to initiate a Selective Call.

Select the channel with the active group alias or ID. See 
Selecting a Channel on page 23.
