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 type 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 running.
