In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when

the screen disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether

the detection circuit operated or not) in order to allow confirmation.

Quickly press the remote command button in the following order from the standby state.
