1.  Select the desired group or channel. 

2.  Place the radio in Private Mode by pressing 

 key, and then follow the selection mode rules. On a 

System radio, the 

 key can be used to toggle the Private Mode ON/OFF. When Private Mode is 

enabled, the   icon is displayed. 

If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, 
the Private Mode will be enabled if forced operation has been programmed in the radio.  

If a group or channel is not programmed for Private Mode operation, 

PVT DIS

 will be displayed if 

an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel 
in Private Mode.  

If the radio does not have the correct encryption key loaded, 

NO KEY#

 will be displayed and the call 

will not be transmitted. 

3.  Continue with standard transmission procedures. A Private Mode access tone will be heard when the 

PTT button is pressed. 

Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang 
time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the 
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same 
group was available in private and entered in the scan list, it can receive clear and private calls, provided 
autoselect was programmed in the radio. The user can select transmitting on the scanned or selected 
group. If a group is entered in the scan list more than once and in different modes (clear, digital, private), 
only the first occurrence of the group will be used.
