Privacy
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 or unscrambled transmissions.
Some radio models may not offer Privacy feature, or may
have a different configuration. Check with your dealer or
system administrator for more information.
Your radio supports two types of privacy, but only one can
be assigned to your radio. They are:
•
Basic Privacy
• Enhanced Privacy
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 different Key Value and Key ID, you either
hear a garbled transmission for Basic Privacy or nothing at
all for Enhanced Privacy.
On a privacy-enabled channel, your radio is able to receive
clear or unscrambled calls, depending on how your radio is
programmed. In addition, your radio may play a warning
tone or not, depending on how it is programmed.
If the radio has a privacy type assigned, the Home Screen
shows the Secure or Unsecure icon, except when the
radio is sending or receiving an Emergency call or alarm.
The green LED lights up when the radio is transmitting, and
blinks rapidly when the radio is receiving an ongoing
privacy-enabled transmission.
NOTICE:
This feature is not applicable in Citizens Band
channels that are in the same frequency.
