If activated by a rise in emperature, the unit will resume operation after cooling off to a normal operating range. If activated by an overload condition, the source of the overload must be found and corrected to resume operation of the amplifier. Most overload conditions are caused by mis-wiring or operation into incorrect speaker loads. Re-check all wiring and connections if this situation occurs and correct as necessary. 3 Level (Gain) Controls 2 Protection Mode LED This LED illuminates red to indicate that the self-protection circuits have been activated and have shut off operation of the amplifier. The protection circuits may be triggered by the temperature of the unit rising above a safe level or by an overload condition. The amplifier is capable of operating from sources supplying a wide range of input levels. The Level controls should initially be set to the mid-rotation position. If it is found that there is not enough output even when the volume control on the car stereo is at its maximum setting, adjust the Level control to increase the output -10-
