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.
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.
• 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.
• 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 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 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. Battery fluid is corrosive and may possibly cause loss of sight or chemical burns.
• 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.
• Use the specified adaptor (PA-3B, PA-3C 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.
• Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.
• 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.
• 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.
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 regulations.
The illustrations as shown in this owner’s manual are for instructional purposes only, and
may be different from the ones on your instrument.
Any mention or reference to the DD-20 in this manual also applies to the model DD-20S.
