PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

Please keep this manual 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 place the power cord near heat sources such as heaters or radiators. Also,

do not excessively bend or otherwise damage the cord, or place heavy objects on
it.

• Only use the voltage specified as correct for the instrument. The required voltage

is printed on the name plate of the instrument.

• Use only the supplied power cord/plug.
• Check the electric plug periodically and remove any dirt or dust which may have

accumulated on it.

• This instrument contains no user-serviceable parts. Do not open the instrument

or attempt to disassemble or modify the internal components in any way. 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,

place on it any containers (such as vases, bottles or glasses) containing liquids
which might spill into any openings. If any liquid such as water seeps into the
instrument, turn off the power immediately and unplug the power cord from the AC
outlet. Then have the instrument inspected by qualified Yamaha service personnel.

• Never insert or remove an electric plug with wet hands.

• Do not put burning items, such as candles, on the unit.

A burning item may fall over and cause a fire.

• When one of the following problems occur, immediately turn off the power switch

and disconnect the electric plug from the outlet. Then have the device inspected
by Yamaha service personnel.
• The power cord or plug becomes frayed or damaged.
• It emits unusual smells or smoke.
• Some object has been dropped into the instrument.
• There is a sudden loss of sound during use of the instrument.

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 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.

• 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.

• Remove the electric plug from the outlet when the instrument is not to be used for

extended periods of time, or during electrical storms.

• Read carefully the attached documentation explaining the assembly process.

Failure to assemble the instrument in the proper sequence might result in damage
to the instrument or even injury.

• Do not place the instrument in an unstable position where it might accidentally fall over.
• When transporting or moving the instrument, always use two or more people.

Attempting to lift the instrument by yourself may damage your back, result in
other injury, or cause damage to the instrument itself.

• Before moving the instrument, remove all connected cables, to prevent damage to

the cables or injury to anyone who might trip over them.

• When setting up the product, make sure that the AC outlet you are using is easily

accessible. If some trouble or malfunction occurs, immediately turn off the power
switch and disconnect the plug from the outlet. Even when the power switch is
turned off, electricity is still flowing to the product at the minimum level. When
you are not using the product for a long time, make sure to unplug the power cord
from the wall AC outlet.

• Though the wooden parts of this instrument have been designed and produced

with care concerning the environment and human health, in some rare instances
customers may sense an unusual odor or develop irritation in the eyes, due to the
coating material and adhesive.
To avoid this, we recommend that you observe the following:
1. Specially ventilate the room for several days after unpacking and installing this

instrument, since it has been packed in airtight conditions in order to maintain
quality during transportation.

2. If the room housing the instrument is small, continue to ventilate it normally,

either daily or periodically.

3. If you have left the instrument in a closed room for a long time under high

temperature, ventilate the room, then lower the temperature if possible, before
using the instrument.

• 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.

• 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 insert a finger or hand in any gaps on the fallboard or instrument. Also

take care that the fallboard does not pinch your finger.

• Never insert or drop paper, metallic, or other objects into the gaps on the

fallboard, panel or keyboard. This could cause physical injury to you or others,
damage to the instrument or other property, or operational failure.

• 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 use the instrument/device or headphones 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.

• Do not place the bench in an unstable position where it might accidentally fall over.
• Do not play carelessly with or stand on the bench. Using it as a tool or stepladder

or for any other purpose might result in accident or injury.

• Only one person should sit on the bench at a time, in order to prevent the

possibility of accident or injury.

• If the bench screws become loose due to extensive long-term use, tighten them

periodically using the included tool.

• Keep special watch over any small children so that they don’t fall off the rear of the

bench. Since the bench does not have a backrest, unsupervised use may result in
accident or injury.
