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.
