DD-65/YDD-60 Owner’s Manual
• Before moving the instrument, remove all connected adaptor and other cables.
•When setting up the product, make sure that the AC outlet you are using is easily
accessible. If some trouble or malfunction occurs, immediately turn off the
power switch and disconnect the plug from the outlet. Even when the power
switch is turned off, electricity is still flowing to the product at the minimum
level. When you are not using the product for a long time, make sure to unplug
the power cord from the wall AC outlet.
• Do not place objects in front of the instrument’s air vent, since this may prevent
adequate ventilation of the internal components, and possibly result in the
instrument overheating.
• 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.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
• Do not insert a finger or hand in any gaps on the instrument.
• 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 use the instrument/device or headphones 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.
