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 the specified adaptor only. Using the wrong adaptor can
result in damage to the product or overheating.
??_??_04
• 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.
??_??_08
• Remove the electric plug from the outlet when the product is
not to be used for extended periods of time.
??_??_09
• Do not touch the product or the electric plug during an
electrical storm.
Connections
• Always read the manuals of the devices to be connected and
follow the directions they contain. Failure to do so may result
in fire, overheating, explosion, or malfunction.
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
??_????_01
• 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
??_????_01
• 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 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.
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
• 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.
