Yamaha EZ-20 [3/74] Caution

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 open the instrument or attempt to disassemble the inter-

nal parts or modify them in any way. The instrument contains

no user-serviceable parts. If it should appear to be malfunc-

tioning, 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 liq-

uids 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 recom-

mended 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 instru-

ment 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 out-

let, 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.

• Always make sure all batteries are inserted in conformity with

the +/- polarity markings. Failure to do so might result in over-

heating, ﬁre, or battery ﬂuid leakage.

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

batteries together with old ones. Also, do not mix battery types,

such as alkaline batteries with manganese batteries, or batter-

ies from different makers, or different types of batteries from

the same maker, since this can cause overheating, ﬁre, or bat-

tery ﬂuid leakage.

• Do not dispose of batteries in ﬁre.

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

charged.

• 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.

• 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. Bat-

tery ﬂuid is corrosive and may possibly cause loss of sight or

chemical burns.

• Before connecting the instrument to other electronic compo-

nents, turn off the power for all components. Before turning the

power on or off for all components, set all volume levels to min-

imum. 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 inter-

ference which can affect proper operation of the other prod-

ucts.

• 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-impreg-

nated 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 attach-

ing the stand, 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 per-

manent hearing loss. If you experience any hearing loss or

ringing in the ears, consult a physician.

• Playing while looking at the lights for a long period of time may

cause eye strain and stiff neck/shoulders. For your health and

comfort, we recommend that you take a ten-minute break for

every hour.

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.

Make sure to discard used batteries according to local regula-

tions.
