PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep this manual in a safe 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:
• 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 (PA-3C or an equivalent
recommended by Yamaha) 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.
• Do not place the AC adaptor cord near heat sources such as
heaters or radiators, and do not excessively bend or otherwise
damage the cord, place heavy objects on it, or place it in a
position where anyone could walk on, trip over, or roll anything
over it.
• Do not open the instrument or attempt to disassemble the
internal parts or modify them in any way. The instrument
contains no user-serviceable parts. 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, or place containers on it containing
liquids which might spill into any openings.
• 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.
• If the AC adaptor cord or plug becomes frayed or damaged, or
if there is a sudden loss of sound during use of the instrument,
or if any unusual smells or smoke should appear to be caused
by it, immediately disconnect the adaptor plug from the outlet,
and have the instrument inspected by qualified Yamaha service
personnel.

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:
• When removing the electric plug from the instrument or an
outlet, always hold the plug itself and not the cord.
• Unplug the AC power adaptor when not using the instrument,
or during electrical storms.
• 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.
• Do not expose the instrument to excessive dust or vibrations,
or extreme cold or heat (such as in direct sunlight, near a
heater, or in a car during the day) to prevent the possibility of
panel disfiguration or damage to the internal components.
• Do not use the instrument in the vicinity of a TV, radio, stereo
equipment, mobile phone, or other electric devices. Otherwise,
the instrument, TV, or radio may generate noise.
• Do not place the instrument in an unstable position where it
might accidentally fall over.
