the dealer where you purchased the unit or from qualified

Yamaha service personnel.

• Be careful not to drop or apply strong impact to this unit. If you

suspect the unit may have been damaged due to dropping or

impact, immediately turn off the power and pull the power plug

from the AC outlet. Failure to observe this may cause electric

shocks, a fire, or malfunctions. Immediately request an

inspection from the dealer where you purchased the unit or from

qualified Yamaha service personnel.

CAUTION

This content indicates “risk of injury.”

■ Power supply/power cord

• Do not use an AC outlet where the power plug fits loosely when

inserted. Failure to observe this may cause a fire, electric

shocks, or burns.

• When removing the electric plug from an AC outlet, always

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

damage it and cause electric shocks or a fire.

• Insert the power plug firmly all the way into the AC outlet.

Using the unit when it is not plugged in sufficiently can cause

dust to accumulate on the plug, causing a fire or burns.

■ Installation

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

accidentally drop or fall over and cause injuries.

• Do not block this unit's ventilation holes (cooling slits). This

unit has ventilation holes on the top/bottom to prevent the

internal temperature from becoming too high. Failure to

observe this may trap heat inside the unit, causing a fire or

malfunctions.

• When installing this unit:

- 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 device in a confined, poorly-ventilated

location.

Failure to observe the above may trap heat inside the unit,

causing a fire or malfunctions. Ensure that there is adequate

space around the unit: at least 30 cm (11-3/4 in) on top, 20 cm

(7-7/8 in) on the sides, and 20 cm (7-7/8 in) on the rear.

• Ensure that the top is facing upwards. Failure to observe this

may cause malfunctions or for the unit to fall and cause injury.

• Do not place the unit in a location where it may come into

contact with corrosive gases or salt air. Doing so may result in

malfunction.

• Avoid being near the unit during a disaster, such as an

earthquake. Since the unit may turn over or fall and cause

injury, quickly move away from the unit and go to a safe place.

• Before moving this unit, be sure to turn off the power switch and

disconnect all connection cables. Failure to observe this may

damage the cables or cause you or someone else to trip and fall.

■ Hearing loss

• Do not use the unit/speakers or 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.

• Before connecting the unit 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 unit LAST, to avoid hearing loss and speaker

damage. When turning the power off the unit should be turned

off FIRST for the same reason. Failure to observe the above

may cause hearing impairment or speaker damage.

■ Maintenance

• Remove the power plug from the AC outlet when cleaning the

unit. Failure to observe this may cause electric shocks.

■ Handling caution

• Do not insert foreign materials such as metal or paper into the

ventilation holes of this unit. Failure to observe this may cause a

fire, electric shocks, or malfunctions. If foreign material gets

into the unit, immediately shut off the power and pull the power

plug from the AC outlet / then turn off any amplifiers and

receivers and request an inspection from the dealer where you

purchased the unit or from qualified Yamaha service personnel.

• Do not rest your weight on the unit or place heavy objects on it.

Avoid applying excessive force to the buttons, switches or

connectors. Failure to observe the above may cause injury or

unit damage.

• Avoid pulling the connected cables to prevent injuries or

damage to the unit by causing it to fall.

■ Battery use

• Always replace all batteries at the same time. Do not use new

batteries together with old ones. Using new ones with old ones

could cause a fire, burns, or inflammation due to fluid leaks.

• Do not mix battery types, such as alkaline batteries with

manganese batteries, or batteries from different makers, or

different types of batteries from the same maker, since this can

cause a fire, burns, or inflammation due to fluid leaks.

• Keep batteries away from children. A child could accidentally

swallow a battery. Failure to observe this may also cause

inflammation due to battery fluid leaks.

• Do not put in a pocket or bag, carry, or store batteries together

with pieces of metal. The battery could short, burst, or leak,

causing a fire or injury.

• Always make sure all batteries are inserted in conformity with

the +/- polarity markings. Failure to do so might result in a fire,

burns, or inflammation due to fluid leaks.

• When the batteries run out, or if the unit is not to be used for a

long time remove the batteries from the remote control to

prevent possible leakage of the battery fluid.

• When storing or discarding batteries, insulate the terminal area

by applying tape, or some other protection. Mixing them with

other batteries or metal objects can cause a fire, burns, or

inflammation due to fluid.

Caution

Do not touch the surface marked with

this label.

The surface may become hot during

operation.
