other liquids,as doing so may result in re or electric shock.
• Use the unit only with the voltage specied on the unit. Using a voltage higher than that
which is specied may result in re 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 re 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.

• To prevent a re or electric shock, never open or 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 re or electric shock.
• Do not insert nor drop metallic objects or ammable materials in the ventilation slots of
the unit’s cover, as this may result in re or electric shock.
Caution
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 re 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 cause damage to the
power cord, resulting in re or electric shock. When removing the power cord, be sure to
hold its plug to pull.
• Do not block the ventilation slots in the unit’s cover. Doing so may cause heat to build up
inside the unit and result in re.
• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct
sunlight, near the heaters, or in locations generating sooty smoke or steam as doing
otherwise may result in re or electric shock.
When the unit is in use
• Should the following irregularity be found during use, immediately switch o the power,
disconnect the power supply plug from the AC outlet and contact your nearest dealer.

the unit’s cover, as this may result in re or electric shock.
• Do not place heavy objects on the unit as this may cause it to fall or break which may
result in personal injury and/or property damage. In addition, the object itself may fall o
and cause injury and / or damage.
• Make sure that the volume control is set to minimum position before power is switched
on. Loud noise produced at high volume when power is switched on can impair hearing.
• Do not operate the unit for an extended period of time with the sound distorting. This is
an indication of a malfunction, which in turn can cause heat to generate and result in a
re.
• Contact your dealer as to the cleaning. If dust is allowed to accumulate in the unit over a
long period of time, a re or damage to the unit may result.
