Press the Menu Select button below 

Load to load the key 

to your radio.

When the key has been loaded successfully, the radio 
sounds a short tone for single-key radios.
OR
When the key has been loaded successfully, the radio 
sounds an alternating tone for multikey radios.

This feature allows the radio to be equipped with different 
encryption keys and supports the DES-OFB algorithm.

There are two types:

Conventional Multikey 

–

 The encryption keys can be tied 

(strapped), on a one-per-channel basis, through Customer 
Programming Software. In addition, you can have operator-
selectable keys, operator-selectable keysets, and operator-
selectable key erasure. If talkgroups are enabled in 
conventional, then the encryption keys are strapped to the 
talkgroups.

Trunked Multikey 

–

 If you use your radio for both 

conventional and trunked applications, you have to strap your 
encryption keys for trunking on a per-talkgroup or 
announcement-group basis. In addition, you may strap a 
different key to other features, such as dynamic regrouping, 
failsoft, or emergency talkgroup. You can have operator-
selectable key erasure.
