Power supply
• 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.
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.

when the product is not to be used for
extended periods of time.

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
• 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 this product out of reach of children.
This product is not suitable for use in
locations where children are likely to be
present.
• To ensure proper heat dissipation of the
product, when installing it:
- Do not cover it with any cloth.
- Make sure the top surface faces up; do
not install on its sides or upside down.
- 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 rear
panel: at least 10 cm above, 10 cm at the
sides and 10 cm 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.
• Before moving the product, remove all
connected cables.
• Do not press the rear panel of the product
against the wall. Doing so may cause the
plug to come in contact with the wall and
detach from the power cord, resulting in
short circuiting, malfunction, or even fire.
Maintenance
• Remove the power plug from the AC outlet
when cleaning the product.
Handling caution
• Do not insert your fingers or hands in any
gaps or openings on the product (ports).
• Do not rest your weight on the product or
place heavy objects on it.
• Do not operate the product if the sound is
distorting. Prolonged use in this condition
could cause overheating and result in fire.
