9. ERROR CODES

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