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 instru-
ment contains no user-serviceable parts. If it should
appear to be malfunctioning, discontinue use immedi-
ately 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 dam-
aged, or if there is a sudden loss of sound during use of
the instrument, or if any unusual smells or smoke
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 confor-
mity with the +/- polarity markings. Failure to do so
might result in overheating, fire, or battery fluid leak-
age.
(4)-7
PRECAUTIONS
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 rec-
ommended 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.
• 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 man-
ganese 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.
