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:

Power supply/AC power adaptor

• 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.

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

is printed on the name plate of the instrument.

• Use the specified adaptor (page 42) only. Using the wrong adaptor can result in

damage to the instrument or overheating.

• Check the electric plug periodically and remove any dirt or dust which may have

accumulated on it.

Do not open

• 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.

Water warning

• 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 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.

Fire warning

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

A burning item may fall over and cause a fire.

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:

Power supply/AC power adaptor

• 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.

Location

• Do not place the instrument in an unstable position where it might accidentally

fall over.

• Before moving the instrument, remove all connected cables.

• 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.

• 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.

PRECAUTIONS

* Please keep this manual in a safe place for future reference.

Battery

• Always replace all batteries at the same time. Do not use new batteries together

with old ones.

• Do not mix battery types, such as alkaline batteries with manganese batteries, or

batteries from different makers, or different types of batteries from the same

maker, since this can cause overheating, fire, or battery fluid leakage.

• Do not tamper with or disassemble batteries.

• Do not dispose of batteries in fire.

• Do not attempt to recharge batteries that are not intended to be charged.

• Keep batteries away from children.

• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid

should come in contact with your eyes, mouth, or skin, wash immediately with

water and consult a doctor. Battery fluid is corrosive and may possibly cause loss

of sight or chemical burns.

• Always make sure all batteries are inserted in conformity with the +/- polarity

markings. Failure to do so might result in overheating, fire, or battery fluid

leakage.

• When the batteries run out, or if the instrument is not to be used for a long time,

remove the batteries from the instrument to prevent possible leakage of the battery

fluid.

If you notice any abnormality

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

and disconnect the electric plug from the outlet. (If you are using batteries,

remove all batteries from the instrument.) 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.

Connections

• 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.

Handling caution

• Do not insert a finger or hand in any gaps on the instrument.

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