When Using the Amplifier
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.
DO NOT place heavy objects on the amplifier, for it may cause it fall and may result
in 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
purposes, when cleaning or leaving the amplifier unused for 7 days or more. Fire or
electric shock may occur.
If the dust accumulates on the power supply plug or in the wall AC outlet, fire may
result in. Clean it periodically. In addition, make sure the plug is inserted in the
wall outlet securely.
Contact your local dealer to clean the dust, it the dust has accumulated in the
amplifier for a long period of time. Dust accumulation may result in fire or damage.
