be programmed for you to initiate a Private Call.

There are two types of Private Calls. The first type, where a 
radio presence check is performed prior to setting up the call, 
while the other sets up the call immediately. 

Only one of these call types can be programmed to your radio 
by your dealer.

You hear a negative indicator tone, when you make a Private 
Call via the Menu, Call Log, Contacts list, One Touch Access

buttons, or the Volume/Channel Knob if this feature is not 
enabled.

individual radio. See Text Messaging Features on page 50 or
