If you use a wired type remote control,
error codes will appear on the remote control display.
If you use a wireless remote control,
the lamp on the photodetector unit will output error
codes by way of blinking patterns.
See the lamp blinking patterns and error codes in the table below.
An error display is displayed only during operation.
