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.
• 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.
