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 precau-
tions include, but are not limited to, the following:
• Do not open the instrument or at-
tempt 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 in-
spected by qualified Yamaha ser-
vice 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.

comes frayed or damaged, or if
there is a sudden loss of sound dur-

appear to be caused by it, immedi-
ately turn off the power switch, dis-
connect the adaptor plug from the
outlet, and have the instrument in-
spected by qualified Yamaha ser-
vice 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, al-
ways 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, al-
ways 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 batter-
ies together with old ones. Also, do
not mix battery types, such as al-
kaline batteries with manganese
batteries, or batteries from different
makers, or different types of batter-
ies 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 batter-
ies that are not intended to be
charged.
