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:
Power supply/Power cord
• 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.

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:
Power supply/Power cord
• 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.
Location
• 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 sides 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.
• Do not place the device in a location where it may come into contact with corrosive
gases or salt air. Doing so may result in malfunction.
• 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 rackmounting" on page 7. 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.
Connections
• 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.
