In the unlikely event that this should happen, unplug the power cord, wait at least 5 seconds, and then plug it again. If the top of this unit is too hot to touch even when no sound is played back, it is necessary to reconsider the installation location. Secure appropriate ventilation so it will not obstruct heat dissipation. En-14
