14. 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 appear on the remote control display. See the lamp blinking patterns and error codes
in the table. An error display is displayed only during operation.
