For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to
bring up past occurrences of failure for confirmation on the screen.

In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen
After you have completed the repairs, clear the result display to “0”.

To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.
