11. ERROR CODES
If you use a wired remote controller, error codes will appear on the remote
controller display.
If you use a wireless remote controller, the lamp on the IR receiver 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.
