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 product. The
required voltage is printed on the name plate of the product.
• Use only the supplied power cord/plug.
If you intend to use the product 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.
• Make sure to fully insert the electric plug to prevent electric
shocks or fire.
• When setting up the product, 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, as long as the power cord is not unplugged from the wall
AC outlet, the product will not be disconnected from the
power source.
• Remove the electric plug from the outlet when the product is
not to be used for extended periods of time.
• Do not touch the product or the electric plug during an
electrical storm.
• Be sure to connect to an appropriate outlet with a protective
grounding connection. Improper grounding can result in
electrical shock, fire, or damage.
Do not open
• This product contains no user-serviceable parts. Do not
attempt to disassemble the internal parts or modify them in
any way.
Water warning/Fire warning
• Do not expose the product 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.
• Never insert or remove an electric plug with wet hands.
• Do not place any burning items or open flames near the
product, since they may cause a fire.
Hearing loss
• Before turning the power of all devices on or off, make sure
that all volume levels are set to the minimum. Failing to do so
may result in hearing loss, electric shock, or device damage.
• When turning on the AC power in your audio system, always
turn on the product LAST, to avoid hearing loss and speaker
damage. When turning the power off, the product should be
turned off FIRST for the same reason.
CAUTION
Always follow the basic precautions listed below to avoid
the possibility of physical injury to you or others. These
precautions include, but are not limited to, the following:
Power supply/Power cord
• When removing the electric plug from the product or an outlet,
always hold the plug itself and not the cord. Pulling by the
cord can damage it.
Location and connection
• Do not place the product in an unstable position or a location
with excessive vibration, where it might accidentally fall over
and cause injury.
• Keep the device out of reach of children. This product is not
suitable for use in locations where children are likely to be
present.
• Do not block the vents. This product has ventilation holes at
the rear to prevent the internal temperature from becoming too
high. In particular, do not place the product on its side or
upside down. Inadequate ventilation can result in overheating,
possibly causing damage to the product(s), or even fire.
• When attempting to dissipate heat on the product, when
installing it, do not use the product in a confined, poorly-
ventilated location.
Inadequate ventilation can result in overheating, possibly
causing damage to the product(s), or even fire. Make sure that
there is adequate space around the product: at least 30cm
above, 30cm at the sides and 30cm behind.
• Do not place the product in a location where it may come into
contact with corrosive gases or salt air. Doing so may result in
malfunction.
