Yamaha DD-65 Manual Do Utilizador

DD-65/YDD-60   Owner’s Manual

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

• 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 (PA-5D, PA-150 or an equivalent recommended by 

Yamaha) 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 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.

• 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 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.

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

A burning item may fall over and cause a fire.

• 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.

• When removing the electric plug from the instrument or an outlet, always hold 

the plug itself and not the cord.

• Unplug the AC power adaptor when not using the instrument, or during 

electrical storms.

• 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.

• 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.

• 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 in the vicinity of a TV, radio, stereo equipment, mobile 

phone, or other electric devices. Otherwise, the instrument, TV, or radio may 
generate noise.

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

fall over.
