Notes:
• The learn procedure is required for the system to function properly, during which, the fob and the base station
exchange the UID and secret keys. The fob UID value is stored in the ATSAMC21-XPRO non-volatile memory
upon completion of this procedure.
• Do not click the Clear button in the System Configuration window as doing so erases all stored UID values.
Without the stored values, the system car access functions, PEPS authentication and RKE messaging do not
operate.
