Thank you for selecting this Yamaha product.
Read this before using the speaker.
• To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
• Install the speaker in a cool, dry, clean place - away from
windows, heat sources, sources of excessive vibration,
dust, moisture and cold. Avoid sources of humming
(transformers, motors). To prevent fire or electrical shock,
do not expose the speaker to rain or water.
• To prevent the enclosure from warping or discoloring, do not
place the speaker where it will be exposed to direct sunlight
or excessive humidity.
• Do not place the following objects on the speaker:
Glass, china, etc.
- If glass etc. falls by vibrations and breaks, it may cause
personal injury.
A burning candle etc.
- If the candle falls by vibrations, it may cause fire and
personal injury.
A vessel with water in it
- If the vessel falls by vibrations and water spills, it may
cause damage to the speaker, and/or you may get an
electric shock.
• Do not place the speaker where foreign objects such as
water drips might fall. It might cause a fire, damage to the
speaker, and/or personal injury.
• Do not place the speaker where it is liable to be knocked
over or struck by falling objects. Stable placement will also
ensure better sound performance.
• Placing the speaker on the same shelf or rack as the
turntable can result in feedback.
• Never put a hand or a foreign object into the port located on
the rear of the speaker as this might cause personal injury
and/or damage to the speaker.
• When moving the speaker, do not hold the port as it might
cause personal injury and/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 speaker may be
damaged.
• When using an amplifier with a rated output power higher
than the nominal input power of the speaker, care should be
taken never to exceed the speaker’s maximum input.
• Do not attempt to clean the speaker with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
• Do not attempt to modify or fix the speaker. Contact
qualified Yamaha service personnel when any service is
needed. The cabinet should never be opened for any
reasons.
• As this unit is heavy, whenever it is moved, two people are
required to transport it safely.
• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for any
accident caused by improper placement or installation
of the speaker.
The speaker is constructed with the majority of the weight
located in its upper portion, and is thus susceptible to falling
over if proper care is not taken to insure its stability. If the
speaker falls over, it may damage the speaker or be the cause
of injury (or even death) to persons and/or damage to personal
property.
For safe and proper use of the speaker:
• Position the speaker in a location that is solid, level, smooth,
and low (with respect to the floor).
• Do not push or apply pressure to the side of the speaker
when moving, or lean objects against the side of the
speaker.
• Do not sit on or set objects on top of the speaker.
Vibrations or jolts associated with earthquakes and other
phenomena or activities may cause the speaker to fall over.
For safety reasons, using commercially available products
that increase stability in the speaker is recommended (metal
fittings or chains, etc.).
Use the stands included with the speaker to increase
stability:
Be sure to use the stands regardless of where the speaker is
positioned. Attaching the stands included with the speaker
reinforces the base of the speaker not to fall over. Please be
cautioned that even though the stands are connected, this
does not guarantee that the speaker will not fall over.
• Place the speakers on a sturdy, vibration-free surface, or on
a well-built stand.
