• Install the speakers in a cool, dry, clean, stable and horizontal

place.

• To avoid electric shock, fire, injury, damage to the speakers, and

discoloration of the cabinet, install away from windows, heat

sources, sources of excessive vibration, dust, moisture, cold, rain,

water, falling objects, noise sources (transformers, motors, etc.)

and direct sunlight.

• Do not insert a hand or object into the port or pick up the speaker

by holding the port, as it may cause personal injury or damage to

the speaker.

• Any time you note distortion, reduce the volume control on your

amplifier to a lower setting. Never allow your amplifier to be

driven into “clipping”. Otherwise the speakers may be damaged.

• When using an amplifier with a rated output power higher than

the nominal input power of the speakers, care should be taken

never to exceed the speakers’ maximum input.

• Do not attempt to clean the speakers with chemical solvents

(ex.alcohol or thinners etc.); this might damage the finish. Use a

clean, dry cloth.

• Do not attempt to modify or fix the speakers. Contact qualified

Yamaha service personnel when any service is needed. The cabi-

net should never be opened for any reasons.

• Secure placement or installation is the owner’s respon-

sibility. Yamaha shall not be liable for any accident

caused by improper placement or installation of speak-

ers.

Check that the following items are included.

Speaker cable (2 m) x 2 / Grille x 2 / Non-skid pads (8 pcs.) x 1

The speaker and the grille are packed

separately. To attach the grille, line up

the projections (magnets) on the reverse

side of the grille with their

corresponding screw heads on the

speaker.

When the grille is removed, be sure not to touch the

speaker units with your hands or to exert excessive force

with tools.

BEFORE MAKING CONNECTIONS, MAKE SURE THAT

THE AMPLIFIER IS SWITCHED OFF.

See page 1 for the connection method.

• Place the speakers on a sturdy, vibration-free surface.

• Better stereo images will be obtained when the speakers are

slightly angled in towards the listening position.

• When placing the speakers on a flat surface, affix the included

non-skid pads to the corners of the speaker undersides, as shown.

The pads will prevent the speaker from moving around.

Placing this unit too close to a CRT TV set might happen

impair picture color or create a buzzing noise. Should

this happen, move the speaker away from the TV set.
