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

• 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.
