Error Codes - Fujitsu ASYG09LECB Installation Manual

15. ERROR CODES

If you use a wireless remote controller, the lamp on the photo detector unit will output er-
ror codes by way of blinking patterns. If you use a wired remote controller, error codes will
appear on the remote controller display. See the lamp blinking patterns and error codes in
the table. An error display is displayed only during operation.
