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 place the power 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.
• Only use the voltage specified as correct for the device. The required voltage is
printed on the name plate of the device.
• Use only the supplied power cord/plug.
If you intend to use the device in an area other than in the one you purchased,
the included power cord may not be compatible. Please check with your Yamaha
dealer.
• Check the electric plug periodically and remove any dirt or dust which may have
accumulated on it.
• Be sure to connect to an appropriate outlet with a protective grounding
connection. Improper grounding can result in electrical shock.
• This device contains no user-serviceable parts. Do not open the device or
attempt to disassemble the internal parts or modify them in any way. If it should
appear to be malfunctioning, discontinue use immediately and have it inspected
by qualified Yamaha service personnel.
• Do not expose the device to rain, use it near water or in damp or wet conditions,
or place on it any containers (such as vases, bottles or glasses) containing
liquids which might spill into any openings. If any liquid such as water seeps
into the device, turn off the power immediately and unplug the power cord from
the AC outlet. Then have the device inspected by qualified Yamaha service
personnel.
• Never insert or remove an electric plug with wet hands.
• Do not put burning items, such as candles, on the unit. A burning item may fall
over and cause a fire.

CAUTION

Always follow the basic precautions listed below to avoid
the possibility of physical injury to you or others, or
damage to the device or other property. These
precautions include, but are not limited to, the following:
• When removing the electric plug from the device or an outlet, always hold the
plug itself and not the cord. Pulling by the cord can damage it.
• Remove the electric plug from the outlet when the device is not to be used for
extended periods of time, or during electrical storms.
• Do not place the device in an unstable position where it might accidentally fall
over.
• Do not block the vents. This device has ventilation holes at the front and side to
prevent the internal temperature from becoming too high. In particular, do not
place the device on its side or upside down. Inadequate ventilation can result in
overheating, possibly causing damage to the device(s), or even fire.
• To avoid damage, do not install or store the device in a place subject to salty air
or corrosive gas or chemicals.
• Before moving the device, remove all connected cables.
• When setting up the device, 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.
• If the device is mounted in an EIA standard rack, carefully read the section
“Precautions for Rack Mounting” on page8. Inadequate ventilation can result in
overheating, possibly causing damage to the device(s), malfunction, or even fire.
• Keep device away from the reach of children.
• Before connecting the device to other devices, turn off the power for all devices.
Before turning the power on or off for all devices, set all volume levels to
minimum.
• Remove the power plug from the AC outlet when cleaning the device.
• Do not insert your fingers or hands in any gaps or openings on the device
(vents, etc.).
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (vents, etc.) If this happens, turn off the power
immediately and unplug the power cord from the AC outlet. Then have the
device inspected by qualified Yamaha service personnel.
• Do not rest your weight on the device or place heavy objects on it, and avoid use
excessive force on the buttons, switches or connectors.
• Do not use speakers 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.
