Requesting an Over-the-Air Rekey (ASTRO Only)
†‡
This feature, also known as
OTAR
, allows your dispatcher to
reprogram the encryption keys in your radio remotely. Your
dispatcher performs the rekey operation upon receiving a rekey
request from you.
Procedure:
1
Press and hold the preprogrammed
Rekey Request
button
to send the rekey request.
2
If the rekey operation fails, a bad-key tone sounds and the
display shows
RKY FAIL
.
Note:
The rekey operation failure indicates that your radio
does not contain the Unique Shadow Key (USK). This
key must be loaded into your radio with the key-
variable loader (KVL) before the rekey request can be
sent.
Refer to your local key management supervisor for
more information.
