PLEASE READ CAREFULLY BEFORE PROCEEDING
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
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.
• 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
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 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 outlet, 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.
• 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
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 adaptor and other
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.

PRECAUTIONS
* Please keep these precautions in a safe place for future reference.
power switch, disconnect the adaptor plug from the outlet, and have the
instrument inspected by qualified Yamaha service personnel.
• Use the specified adaptor (PA-5C, PA-D12 or an equivalent recommended
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.
• 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 "Battery voltage is low"
will display in the LCD. When this happens, immediately back up your data
(using an external device such as the floppy disk-based Yamaha MIDI Data
Filer MDF3), 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 Memory Card (SmartMedia) frequently, in order to
help prevent the loss of important data due to a malfunction or user
operating error.
• Save all data to an external device such as the Yamaha MIDI Data Filer
MDF3, 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.
