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 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
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.
