When the key has been loaded successfully, one of
the following scenarios occurs:
• You hear the radio sounds a short tone for single-
key radios.
• You hear the radio sounds an alternating tone for
multikey radios.
The KVL indicates that keyload is successful.
Multikey Feature
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 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 the Selected Encryption Keys
This feature allows you to erase all or selected
encryption keys.
Erasing the single key in radios with the single-key
option and erasing all keys in radios with the
multikey option via the preprogrammed
