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:
If you notice any abnormality
• If any of the following problems occur, immediately turn off the
power switch and disconnect the electric plug from the outlet.
- The power cord or plug becomes frayed or damaged.
- Unusual smells or smoke are emitted.
- Some object, or water has been dropped into the product.
- There is a sudden loss of sound during use of the product.
- Cracks or other visible damage appear on the product.
Then have the product inspected or repaired by qualified
Yamaha service personnel.
Power supply/AC adaptor
• 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 the specified adaptor only. Using the wrong adaptor can
result in damage to the product or overheating.
• 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.
• 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 connecting the product to other devices, turn off the
power for all devices. Also, 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 power amplifier LAST, to avoid hearing loss and
speaker damage. When turning the power off, the power
amplifier should be turned off FIRST for the same reason.
• Do not use headphones 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.
CAUTION
Always follow the basic precautions listed below to avoid
the possibility of physical injury to you or others, or
damage to the product or other property. These
precautions include, but are not limited to, the following:
Power supply/AC adaptor
• Do not cover or wrap the AC adaptor with a cloth or blanket.
• 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 where it
might accidentally fall over and cause injuries.
• Do not block the vents. This product has ventilation holes at
the top/rear/sides/bottom 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 cover it with any cloth.
- Do not install it on a carpet or rug.
- 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.
