• Take care that the key cover does not pinch your fingers, and do not
insert a finger or hand in the key cover gap.
• Never insert or drop paper or metallic or other objects between the slits of
the key cover and the keyboard. If this happens, immediately turn off the
power and remove the electric plug from the outlet and have the instru-
ment inspected by qualified Yamaha service personnel.
• Do not place the instrument against a wall (allow at least 3 cm/one-inch
from the wall), since this can cause inadequate air circulation, and possi-
bly result in the instrument overheating.
• Read carefully the attached documentation explaining the assembly pro-
cess. Failure to assemble the instrument in the proper sequence might
result in damage to the instrument or even injury.
• Do not operate the instrument for a long period of time at a high or un-
comfortable volume level, since this can cause permanent hearing loss. If
you experience any hearing loss or ringing in the ears, consult a physi-
cian.

■USING THE BENCH (if included)

• Do not play carelessly with or stand on the bench. Using it as a tool or
step-ladder or for any other purpose might result in accident or injury.
• Only one person should sit on the bench at a time, in order to prevent the
possibility of accident or injury.
• Do not attempt to adjust the bench height while sitting on the bench,
since this can cause excessive force to be imposed on the adjustment
mechanism, possibly resulting in damage to the mechanism or even in-
jury.
• If the bench screws become loose due to extensive long-term use, tighten
them periodically using the included tool.

■SAVING USER DATA

• Save all data to an external device such as the Yamaha DOU-10 Disk
Orchestra Unit in order to help prevent the loss of important data due to a
malfunction or user operating error.
Yamaha cannot be held responsible for damage caused by improper use or modi-
fications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep these precautions 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 internal parts
or modify them in any way. The instrument contains no user-serviceable
parts. If it should appear to be malfunctioning, discontinue use immedi-
ately 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.
• If the power 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 electric plug from the outlet, and have the instru-
ment inspected by qualified Yamaha service personnel.
• Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
• 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

instrument or other property. These precautions include, but are not limited to, the following:

• Do not place the power cord near heat sources such as heaters or radia-
tors, 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 an outlet, always hold the plug
itself and not the cord. Pulling by the cord can damage it.
• 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.
• Remove the electric plug from the outlet when the instrument is not to be
used for extended periods of time, or during electrical storms.
• Before connecting the instrument to other electronic components, turn off
the power for all components. Before turning the power on or off for all
components, set all volume levels to minimum.
• 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 televi-
sions, radios, or speakers, since this might cause interference which can
affect proper operation of the other products.
• Do not place the instrument in an unstable position where it might acci-
dentally fall over.
• Before moving the instrument, remove all connected cables.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint
thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths.
Also, do not place vinyl or plastic objects on the instrument, since this
might discolor the panel or keyboard.
• Gently remove dust and dirt with a soft cloth. Do not wipe too hard since
small particles of dirt can scratch the instrument’s finish.
• Bumping the surface of the instrument with metal, porcelain, or other hard
objects can cause the finish to crack or peel. Use caution.
• 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.
