* Please keep this manual in a safe place for future reference.

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:

• Only use the voltage speciﬁed as correct for the device. The required

voltage is printed on the name plate of the device.

• Use only the included 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.

• Be sure to connect to an appropriate outlet with a protective grounding

connection. Improper grounding can result in electrical shock.

• Do not open the device or attempt to disassemble the internal parts or

modify them in any way. The device contains no user-serviceable parts.

If it should appear to be malfunctioning, discontinue use immediately

and have it inspected by qualiﬁed Yamaha service personnel.

• Do not expose the device to rain, use it near water or in damp or wet

conditions, or place containers on it containing liquids which might

spill into any openings. If any liquid such as water seeps into the

device, turn off the power immediately and unplug the power cord from

the AC outlet. Then have the device inspected by qualiﬁed Yamaha

service personnel.

• Never insert or remove an electric plug with wet hands.

�� If the power cord or plug becomes frayed or damaged, or if there is a

sudden loss of sound during use of the device, or if any unusual smells

or smoke should appear to be caused by it, immediately turn off the

power switch, disconnect the electric plug from the outlet, and have the

device inspected by qualiﬁed Yamaha service personnel.

• If this device should be dropped or damaged, immediately turn off the

power switch, disconnect the electric plug from the outlet, and have the

device inspected by qualiﬁed Yamaha service personnel.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or

damage to the device or other property. These precautions include, but are not limited to, the following:

• Remove the electric plug from the outlet when the device is not to be

used for extended periods of time, or during electrical storms.

• When removing the electric plug from the device or an outlet, always

hold the plug itself and not the cord. Pulling by the cord can damage it.

• Always consult qualiﬁed Yamaha service personnel if the device

installation requires construction work, and make sure to observe the

following precautions.

- Choose mounting hardware and an installation location that can support

the weight of the device.

-Avoid locations that are exposed to constant vibration.

- Inspect the device periodically.

• Before moving the device, remove all connected cables.

• When setting up the device, 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, electricity is still ﬂowing to the

product at the minimum level. When you are not using the product for a

long time, make sure to unplug the power cord from the wall AC outlet.

• Do not use the device in a conﬁned, poorly-ventilated location. Make

sure that there is adequate space between the device and surrounding

walls or other devices: at least 30cm at the sides, 30cm behind and

30cm above. Inadequate ventilation can result in overheating, possibly

causing damage to the device(s), or even ﬁre.

• Do not expose the device to excessive dust or vibrations, or extreme

cold or heat (such as in direct sunlight, near a heater, or in a car during

the day) to prevent the possibility of panel disﬁguration or damage to

the internal components.

• Do not place the device in an unstable position where it might

accidentally fall over.

• Do not block the vents. This device has ventilation holes at the rear to

prevent the internal temperature from becoming too high. Inadequate

ventilation can result in overheating, possibly causing damage to the

device(s), or even ﬁre.

• Before connecting the device to other devices, turn off the power for all

devices. Before turning the power on or off for all devices, set all

volume levels to minimum.
