Secure radio operation provides the highest commercially 
available level of voice security on both trunked and 
conventional channels.

Unlike other forms of security, Motorola digital encryption 
provides signaling that makes it virtually impossible for others to 
decode any part of an encrypted message.

Procedure:
Press the preprogrammed Secure/Clear button to the secure 
position.

If the selected channel is preprogrammed for clear-only 
operation – when you press the PTT button, you hear 
an invalid mode tone and the display shows Clear TX 
only.

The radio will not transmit until you set the Secure/
Clear button to the clear position.

Procedure:
Turn the preprogrammed Secure/Clear button to the clear 
position.

If the selected channel is preprogrammed for secure-
only operation – when you press the PTT button, you 
hear an invalid mode tone and the display shows 
Secure TX only.

The radio will not transmit until you set the Secure/
Clear button to the secure position.

Refer to the key-variable loader (KVL) manual for 
equipment connections and setup.

Attach the KVL to your radio. 

The display shows Keyloading, and all other radio 
functions, except for power down, backlight, and volume, 
are locked out.
