When Installing the Unit

• Do not expose the unit to rain or an environment

where it may be splashed by water or other liquids,
as doing so may result in fire or electric shock. 

• Use the unit only with the voltage specified on the

unit. Using a voltage higher than that which is
specified may result in fire or electric shock.

• 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 the voltage of up
to 100 V is applied to the high impedance speaker
terminals, never touch these terminals to avoid
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 
· 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
qualified service personnel.

• 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. 

• Do not touch during thunder and lightning, as this

may result in electric shock. 

• When replacing the fuse, be sure to use the

supplied one. Using any other fuse than supplied
may cause fire or electric shock.

When Installing the Unit

• Never plug in nor remove the power supply plug

with wet hands, as doing so may cause electric
shock.

• When unplugging the power supply cord, be sure

to grasp the power supply plug; never pull on the
cord itself. Operating the unit with a damaged
power supply cord may cause a fire or electric
shock.

• When moving the unit, be sure to remove its power

supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may
