Multikey Feature

This feature allows the radio to be equipped with different encryption keys.
There are two types of encryption keys:
Conventional Multikey
The encryption keys are strapped on a one-per-channel basis, through CPS. 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 the radio is used for both conventional and trunked applications, strap the encryption keys for
trunking on a per-talkgroup or announcement-group basis. In addition, a different key can be
strapped to other features, such as dynamic regrouping, failsoft, or emergency talkgroup. You can
have operator-selectable key erasure.
