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
disassemble 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 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 instrument
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 16.)
• 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 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 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 televisions,
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
accidentally 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, 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/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.
• Do not operate the instrument for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing loss. If
you experience any hearing loss or ringing in the ears, consult a physician.
■ REPLACING THE BACKUP BATTERY
• This instrument contains a non rechargeable internal backup battery which
permits internal data to remain stored even when the power is off. When the
backup battery needs replacing, the message "Change internal battery!" will
display in the LCD. When this happens, immediately back up your data, then
have qualified Yamaha service personnel replace the backup battery.
• Do not attempt to replace the backup battery yourself, in order to prevent the
possible serious hazards. Always have qualified Yamaha service personnel
replace the backup battery.
• Never place the backup battery in a location that a child can reach, since a
child might accidentally swallow the battery. If this should happen, consult a
physician immediately.
■ 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.
