PLEASE READ CAREFULLY BEFORE PROCEEDING
Please keep this manual in a safe and handy place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from
electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not
limited to, the following:
Power supply
• Do not place the power cord near heat sources such as
heaters or radiators. Also, do not excessively bend or
otherwise damage the cord, or place heavy objects on it.
• Do not touch the product or the power plug during an
electrical storm.
• Use only the correct voltage specified for the product. The
required voltage is printed on the name plate of the
product.
• Use the specified adaptor (page 69).
• Check the power plug periodically and remove any dirt or
dust which may have accumulated on it.
• Insert the power plug firmly all the way into the AC outlet.
Using the product when it is not plugged in sufficiently can
cause dust to accumulate on the plug, possibly resulting in
fire or skin burns.
• When setting up the product, make sure that the AC outlet
you are using is easily accessible. If some trouble or
malfunction occurs, immediately turn off the power switch
and disconnect the plug from the outlet. Even when the
power switch is turned off, as long as the power cord is not
unplugged from the wall AC outlet, the product will not be
disconnected from the power source.
• Do not connect the product to an electrical outlet using a
multi-plug outlet extender. Doing so can result in lower
sound quality, or possibly cause overheating in the outlet.
• When disconnecting the power plug, always hold the plug
itself and not the cord. Pulling by the cord can damage it
and cause electric shocks or a fire.
• If not using the product for long periods of time, be sure to
pull the power plug from the AC outlet.
Do not disassemble
• Do not attempt to disassemble the internal parts or modify
them in any way.
Water warning
• Do not expose the product to rain, use it near water or in
damp or wet conditions, or place on it any containers (such
as vases, bottles or glasses) containing liquids which might
spill into any openings or places where water may drop. A
liquid such as water getting into the product may cause a
fire, electric shocks, or malfunctions.

pressure, cold or heat (such as in direct sunlight or a fire) or
excessive dust or humidity.
Doing so may result in the battery bursting, causing a fire or
injury.
• Follow the precautions below. Failure to do so might result
in battery fluid leakage. If the contents of the battery gets
on your hands or in your eyes, it can cause blindness,
chemical burns, and damage of the product.
- Use the specified battery type (page 69) only.
