Note If the error continues for 3 hours or longer, the replacement notification func-
tion will be disabled. Even if the cause of the overheating is removed, the dis-
play will continue as "Hot," and the notification output will remain OFF. In this
state, the internal parts may deteriorate even if the PC operation is normal, so
replace the Power Supply Unit.
