13. ERROR CODES

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 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.
