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:
• Use only the stand 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 Memory Card (SmartMedia) 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.
• 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 12.)
• 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. 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 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.
