heat protection, no signal output at the time and over-heat inside the unit (the
surface temperature of power transistor is 110 ), the temperature must be
lowered through better ventilation and decrease the signal level etc. After the
temperature dropped, the protection stop and meanwhile the LED turns off with
the unit recover normal work.
