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:
• 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.
• Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
• Use the specified adaptor (page 88) only. Using the wrong adaptor can
result in damage to the instrument or overheating.
• Check the electric plug periodically and remove any dirt or dust which
may have accumulated on it.
• This instrument contains no user-serviceable parts. Do not open the
instrument or attempt to disassemble or modify the internal components
in any way. If it should appear to be malfunctioning, discontinue use
immediately and have it inspected by qualified Yamaha service
personnel.
• Do not expose the instrument to rain, use it near water or in damp or wet
conditions, place on it any containers (such as vases, bottles or glasses)
containing liquids which might spill into any openings. If any liquid such
as water seeps into the instrument, turn off the power immediately and
unplug the power cord from the AC outlet. Then have the instrument
inspected by qualified Yamaha service personnel.
• Never insert or remove an electric plug with wet hands.
• Do not put burning items, such as candles, on the unit. A burning item
may fall over and cause a fire.
• When one of the following problems occur, immediately turn off the
power switch and disconnect the electric plug from the outlet. Then have
the device inspected by Yamaha service personnel.
- The power cord or plug becomes frayed or damaged.
- It emits unusual smells or smoke.
- Some object has been dropped into the instrument.
- There is a sudden loss of sound during use of the instrument.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or
damage to the instrument or other property. These precautions include, but are not limited to, the following:
• Do not connect the instrument to an electrical outlet using a multiple-
connector. Doing so can result in lower sound quality, or possibly cause
overheating in the outlet.
• When removing the electric plug from the instrument or an outlet, always
hold the plug itself and not the cord. Pulling by the cord can damage it.
• Remove the electric plug from the outlet when the instrument is not to be
used for extended periods of time, or during electrical storms.
• Do not place the instrument in an unstable position where it might
accidentally fall over.
• Before moving the instrument, remove all connected cables, to prevent
damage to the cables or injury to anyone who might trip over them.
• 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, electricity is still flowing to the
product at the minimum level. When you are not using the product for a
long time, make sure to unplug the power cord from the wall AC outlet.
• Use only the stand/rack specified for the instrument. When attaching the
stand or rack, use the provided screws only. Failure to do so could cause
damage to the internal components or result in the instrument falling
over.
