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:

• 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 power switch,

disconnect the adaptor plug from the outlet, and have the instrument inspected

by qualiﬁed Yamaha service personnel.

• Use the speciﬁed adaptor (PA-3B 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.

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.

• 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 “!BatteryLo” 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

• 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.
