Specifications

 Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid 

using the power cord in close proximity to heaters, and never place heavy objects -- including 

the unit itself -- on the power cord, as doing so may result in fire or electric shock.

 Be sure to replace the unit's terminal cover after connection completion. Because high 

voltage is applied to the speaker terminals, never touch these terminals to avoid electric 

shock.

 Be sure to ground to the safety ground (earth) terminal to avoid electric shock. Never 

ground to a gas pipe as a catastrophic disaster may result.

 Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a 

slanted surface. Doing so may result in the unit falling down, causing personal injury and/or 

property damage.

·If the unit falls, or the unit case breaks.

·If the power supply cord is damaged (exposure of the core, disconnection, etc.)

·If it is malfunctioning (no tone sounds.)

 To prevent a fire or electric shock, never open nor remove the unit case as there are high 

voltage components inside the unit. Refer all servicing to your nearest dealer.

 Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. 

If they accidentally spill into the unit, this may cause a fire or electric shock.

 Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the

unit's cover, as this may result in fire or electric shock.

When the Unit is in Use

 Should the following irregularity be found during use,immediately switch off the 

power,disconnect the power supply plug from the AC outlet and contact your nearest 

dealer.Make no further attempt to operate the unit in this condition as this may cause fire or 

electric shock.

·If you detect smoke or a strange smell coming from the unit.

·If water or any metallic object gets into the unit.
