1. Press  until REKY 
appears.
2. Press 
 below 
REKY.
REQUEST REKY is 
displayed.
3. Press the PTT button 
to send the rekey 
request.
PLEASE WAIT is 
displayed.
4. One of the following 
occurs:
The radio sounds five 
tones when the 
dispatcher has 
received the request.
NOTE:Any subsequent pressing of the PTT button will exit 
the feature and allow you to transmit in the normal 
manner. Pressing 
 or the emergency button also 
exits the feature.
If the display 
momentarily shows 
REKEY FAIL and a 
bad-key tone sounds, 
the rekey operation 
failed because the 
radio does not contain 
the Unique Shadow 
Key (USK).
You have to load the 
USK into the radio 
using the KVL before 
the radio can be 
reprogrammed over 
the air.
NOTE:If you exit at this point, but stay on the current channel 
in the dispatch mode, the radio momentarily shows 
REKEYED or DENIED and sounds a tone indicating the 
status of the rekey request.
