Next press 0, 1, 2, 3 and top right keys, in sequence. The Diagnosis menu should be displayed.
Enter 99 and press the top right key. A message should be displayed saying "Input Mode No":
Next press 1 and top right key to EEPROM format. The following messages should appear (wait about 2 minutes):

Wait until all the above messages are displayed and then press the top right key.
