1) This section describes the diagnostic method for each check code displayed on the remote controller.
2) In some cases, a check code indicates multiple symptoms.
In this case, confirm LED display on the outdoor P.C. board to narrow the contents to be confirmed.
3) The check code on the remote controller is displayed only when the same error occurred continuously by
multiple times while LED of the outdoor P.C. board displays even an error which occurred once.
Therefore the display on the remote controller may differ from that of LED.
