If you use a wireless remote control,
the lamp on the photo detector unit will output error
codes by way of blinking patterns.
If you use a wired remote control,
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.
