* If a trouble is detected upon power on, CPU turns off the speaker relay. And if the trouble is not recovered within 2
seconds, CPU turns the unit into stand-by. If DC offset or over-current is detected on power on status, the speaker
relay is turned off, and if over-heat, trouble in main transformer is detected, the unit turns into stand-by immediately.
