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
• 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.
• 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
• 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.
Fire warning
• 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
• 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.
• 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.
• To ensure proper heat dissipation of the product, when
installing it:
- Do not cover it with any cloth.
- 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 from the rear: at least 30 cm
above, 30 cm at the sides and 30 cm behind.
