Multikey Feature

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

Erasing Encryption Keys

If the Multi-system Over-the-Air Rekeying feature is in use, the keys erased are only for the current
secure profile of the selected channel. The erase all option operates as configured by the dealer or
system administrator. Erasing all keys using the Top (Orange) button and the Top Side (Select) button
erases all keys in all keylists in the radio.
Procedure:
• Erasing the single key in radios with the single-key option and erasing all keys in radios with the
multikey option by using the preprogrammed Top Side (Select) button and Top (Orange)
button:
a. Press and hold the Top Side (Select) button.
b. While holding Top Side (Select) button down, press the Top (Orange) button.
The display shows PLS WAIT. When all the encryption keys have been erased, the display
shows ALL ERASED.
NOTICE: Do not press the Top (Orange) button before pressing the Top Side
(Select) button, unless you are in an emergency situation as this sends an
emergency alarm.
