•  Rotate the TUNE knob to change the encryption key.  A value of “PSET” indicates you want to use the

specified key.

•  When transmitting, a if encryption keys are properly loaded, a tone at the start of the transmission will be

will be lost.

•  When transmitting in the encrypted mode, if you hear a continuous warble tone, this indicates that the

encryption key(s) have not been loaded.  Either manually enter encryption keys or perform an OTAR if your
system has that capability.

•  The newly selected KEYMAT WILL REMAIN even if the channel is changed in effect until power down.

•  Ensure you are on the HOME PAGE, and the cursor is on the line of the radio you wish to select and an OTAR

capable channel is also selected.

•  To confirm the start of the OTAR, select YES and press the ENTER button to initiate the OTAR process.  The

status of the OTAR will be displayed on the radio’s display line.  Status messages include “OTAR
REQUESTED”, “OTAR IN PROGRESS”, “OTAR ABORTING”, “OTAR COMPLETE”, and “OTAR
