Make sure that the volume control is turned to minimum position before power is
switched on. Loud sound produced at high volume when power is switched
on may impair hearing.

body injury and/or property damage. Besides, the object itself may cause
damaged or body injury.
DO NOT operate the amplifier for the extended period of time with the sound distorting.
It is an indication of malfunction, which can cause heat and result in fire.
Switch the power off, and unplug the power supply plug from the AC outlet for safety
