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:
Do not open the instrument or attempt to disassemble the inter-
nal parts or modify them in any way. The instrument contains
no user-serviceable parts. If it should appear to be malfunc-
tioning, 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 liq-
uids which might spill into any openings.
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 turn off the power switch, disconnect the
adaptor plug from the outlet, and have the instrument
inspected by qualified Yamaha service personnel.
Use the specified adaptor (PA-3B or an equivalent recom-
mended by Yamaha) only. Using the wrong adaptor can result
in damage to the instrument or overheating.
Before cleaning the instrument, always remove the electric
plug from the outlet. Never insert or remove an electric plug
with wet hands.
Check the electric plug periodically and remove any dirt or dust
which may have accumulated on it.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the instru-
ment or other property. These precautions include, but are not limited to, the following:
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.
When removing the electric plug from the instrument or an out-
let, always hold the plug itself and not the cord.
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.
Unplug the AC power adaptor when not using the instrument,
or during electrical storms.
Always make sure all batteries are inserted in conformity with
the +/- polarity markings. Failure to do so might result in over-
heating, fire, or battery fluid leakage.
Always replace all batteries at the same time. Do not use new
batteries together with old ones. Also, do not mix battery types,
such as alkaline batteries with manganese batteries, or batter-
ies from different makers, or different types of batteries from
the same maker, since this can cause overheating, fire, or bat-
tery fluid leakage.
Do not dispose of batteries in fire.
Do not attempt to recharge batteries that are not intended to be
charged.
• When the batteries run out, or if the instrument is not to be
used for a long time, remove the batteries from the instrument
to prevent possible leakage of the battery fluid.
Keep batteries away from children.
If the batteries do leak, avoid contact with the leaked fluid. If
the battery fluid should come in contact with your eyes, mouth,
or skin, wash immediately with water and consult a doctor. Bat-
tery fluid is corrosive and may possibly cause loss of sight or
chemical burns.
• Before connecting the instrument to other electronic compo-
nents, turn off the power for all components. Before turning the
power on or off for all components, set all volume levels to min-
imum. Also, be sure to set the volumes of all components at
their minimum levels and gradually raise the volume controls
while playing the instrument to set the desired listening level.
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 near other electrical products such
as televisions, radios, or speakers, since this might cause inter-
ference which can affect proper operation of the other prod-
ucts.
• Do not place the instrument in an unstable position where it
might accidentally fall over.
• Before moving the instrument, remove all connected adaptor
and other cables.
When cleaning the instrument, use a soft, dry cloth. Do not use
paint thinners, solvents, cleaning fluids, or chemical-impreg-
nated wiping cloths. Also, do not place vinyl, plastic or rubber
objects on the instrument, since this might discolor the panel or
keyboard.
Do not rest your weight on, or place heavy objects on the
instrument, and do not use excessive force on the buttons,
switches or connectors.
Use only the stand specified for the instrument. When attach-
ing the stand, use the provided screws only. Failure to do so
could cause damage to the internal components or result in the
instrument falling over.
• Do not operate the instrument for a long period of time at a
high or uncomfortable volume level, since this can cause per-
manent hearing loss. If you experience any hearing loss or
ringing in the ears, consult a physician.
Playing while looking at the lights for a long period of time may
cause eye strain and stiff neck/shoulders. For your health and
comfort, we recommend that you take a ten-minute break for
every hour.
Yamaha cannot be held responsible for damage caused
by improper use or modifications to the instrument, or
data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Make sure to discard used batteries according to local regula-
tions.
