Privacy
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 to 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).
The LED lights up solid green while the radio is transmitting and
double blinks green when the radio is receiving an ongoing
privacy-enabled transmission.
NOTE: Some radio models may not offer this Privacy feature.
Check with your dealer or system administrator for
more information.
