Motorola SL4000 用户手册

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. 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/locations may not offer this Privacy 

feature. Check with your dealer or system administrator 
for more information.
