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.
•
Use the specified adaptor (PA-3B 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.
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.
•
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.
(3)-6
•
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-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.
