Motorola XPR 5550 manual Privacy

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 green LED lights up while the radio is transmitting and double blinks 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.
