Motorola SSETM 5000 service manual Load an Encryption Key, Multikey Feature

Chapter 6 Encryption

This chapter describes the encryption capability of the SSE 5000 radio.

6.1Load an Encryption Key

To load an encryption key:

1.Refer to the key-variable loader (KVL) manual for equipment connections and setup.

2.Attach the KVL to the radio. The display shows “KEYLOAD.” All other radio functions, except for power down, backlight, and volume, are locked out.

3.Refer to the KVL manual for how to load the encryption keys into the radio.

4.When the key is loaded successfully, you will hear:

•On single-key radios—a short tone.

•On multikey radios—an alternating tone.

6.2Multikey Feature

This feature allows the radio to be equipped with multiple encryption keys. The encryption keys can be tied (strapped), on a one-per-channel basis. It can support up to three different encryption algorithms simultaneously (DES, DES-XL and DES-OFB).
