If enabled, this feature helps to prevent eavesdropping by 
unauthorized users on a channel by the use of a software-
based scrambling solution. The signaling and user identification 
portions of a transmission are not scrambled.

Your radio must have privacy enabled on the channel to 
send a privacy-enabled transmission, although this is not a 
necessary requirement for receiving a transmission. While on a 
privacy-enabled channel, the radio is still able to receive clear 
(unscrambled) transmissions.

Your radio supports two types of privacy:

Basic Privacy

Enhanced Privacy

Only ONE of the privacy types above can be assigned to the 
radio.

To unscramble a privacy-enabled call or data transmission, your 
radio must be programmed have the same Privacy Key (for 
Basic Privacy), or the same Key Value and Key ID (for 
Enhanced Privacy) as the transmitting radio.

If your radio receives a scrambled call that is of a different 
Privacy Key, or a different Key Value and Key ID, you will either 
hear a garbled transmission (Basic Privacy) or nothing at all 
(Enhanced Privacy).
