fire or electric shock. 

 

DO NOT touch the power supply plug during thundering and lightning, for it may result 

in electric shock. 

 

DO NOT insert or drop the metallic objects or flammable materials into the ventilation 

slots of the amplifier, for it may result in fire or electric shock. 

 

DO NOT open nor remove the amplifier cover to prevent fire or electric shock, for there

When Installing the Amplifier 

 

 

DO NOT remove nor plug in the power supply plug with wet hands, for it may cause 

electric shock. 

 

When unplug the power supply cord, be sure to grasp the power supply plug.    DO 

NOT pull on the cord itself.    Operating the amplifier with damaged power 

supply cord may cause fire or electric shock. 

 

Avoid installing the amplifier in humid or dusty places, the area exposed to the direct 

sunlight, locations generating smoke or steam, or the spot near the heaters.   

It may result in fire or electric shock. 

 

When moving the amplifier, be sure to remove its power supply cord from the wall 

outlet.    Moving the amplifier with the power cord connected to the outlet may 

cause damage to the power cord, and resulting in fire or electric shock.   

When removing the power cord, be sure to grasp its plug to pull. 

 

DO NOT block the ventilation slots of the amplifier chassis.    It will cause the 

temperature rising and result in fire.
