Over-the-Air Rekeying (Rekey Request) (ASTRO Conventional

The over-the-air rekeying (OTAR) feature allows the dispatcher to
reprogram the encryption keys in the radio remotely. The dispatcher
performs the rekey operation upon receiving a rekey request from the
user.
Use the Menu
1 Press U to find REKY.
2 Press D, E, or F directly
below REKY.
3 Press the PTT to send the
rekey request.
Note: Pressing the PTT again, or the Home or Emergency
button, will exit the feature and allow the user to
transmit in the normal manner.
4 If the display shows REKEY
FAIL and a bad-key tone
sounds, the rekey operation has
failed.
Note: If this occurs, your radio does not contain the Unique
Shadow Key (USK). This key must be loaded into the
radio with the key-variable loader (KVL) before the
rekey request can be sent. Refer to your local key
management supervisor for more information.
