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:
• This instrument contains no user-serviceable parts. Do not attempt to dis-
assemble or modify the internal components in any way.
• 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 sud-
den 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.
• Always connect the three-pin attachment plug to a properly grounded
power source. (For more information about the main power supply, see
page 14.)
• 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 the instrument or 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-con-
nector. Doing so can result in lower sound quality, or possibly cause over-
heating 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. 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 inter-
nal 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 thin-
ners, solvents, cleaning fluids, or chemical-impregnated 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.
• Do not place objects in front of the instrument's air vent, since this may
prevent adequate ventilation of the internal components, and possibly
result in the instrument overheating.
• Do not operate the instrument for a long period of time at a high or uncom-
fortable volume level, since this can cause permanent hearing loss. If you
experience any hearing loss or ringing in the ears, consult a physician.
■SAVING USER DATA
• Always save data to a floppy disk frequently, 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 modifications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
