Multikey
The multikey feature allows your radio to be equipped with as many
as 48 different encryption keys and supports the DES-OFB algorithm.
• Conventional Multikey — The encryption keys can be tied
(strapped), on a one-per-channel basis, through radio service
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 will 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,

encryption keys into your
radio. When the key has

heard.
