It may be desirable to erase the encryption keys contained in a P-2000 transceiver.  For example, prior to sending the 
unit in for service.  This can be accomplished as follows. 

•  Ensure you are on the HOME PAGE, and the cursor is on an encryption capable channel. 

•  Press the PROG button.  If prompted, enter the password #1 (In the system programming, the user has the 

option of eliminating this password by setting it to “0000”) 

 

 

•  When prompted, enter the password #2 and the Transceiver Setup page will be displayed as below: 
 

 

•  In the XCVR field, select which transceiver (FM1 or FM2) to erase keys. 

•  Highlight the START option and press the enter button to erase the encryption keys. 

•  Upon completion of the process the unit will display a dialog box indicating that it needs to be restarted, 

highlight YES and press the enter button to restart the unit . After the unit restarts, verify that the keys have 
been erased by attempting to transmit on an encryption channel with PVT on.  The transceiver will provide an 
audio tone to indicate encryption keys have been erased.
