Read these precautions carefully before using your
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. To clean,
wipe with a dry, soft cloth.
●
To prevent the enclosure from warping or
discoloring, do not place the speaker where it will be
exposed to direct sunlight or excessive humidity.
●
When the front cover is removed, take care not to
touch the speaker units with your hands or to exert
excessive force with tools.
●
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.
●
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.
●
This speaker features a magnetically shielded
design, but there is still a chance that placing it too
close to a TV set might impair picture color. Should
this happen, move the speaker away from the TV
set.
PRECAUTIONS
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.).
PRECAUTIONS WHEN POSITIONING THE SPEAKERS
Use the stands included with the speakers to
increase stability:
●
Stands
Be sure to use the stands regardless of where the
speakers are positioned. Attaching the stands
included with the speakers 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
speakers will not fall over.

HOW TO USE THE
ACCESSORIES INCLUDED
WITH THE SPEAKERS
■ Attaching the stand
When positioning the speakers, be sure to use the
stand to increase stability.
Use the 8 specified holes located on the base of the
speaker.
Procedure:
➀
Put the 4 mm tapping screws through the two
holes on the stand, and screw into the two holes
on the base of the speaker.
②
When both screws have been attached, tighten
both of the screws so that the stand is firmly in
place.
Be sure to check that the stand is firmly attached.
③
Attach the pads to the bottom of the end portion of
the stand.
④
Attach the other stands in the same manner and
confirm that all 4 stands have been firmly
attached.
⑤
Place the speaker in the desired location.
Note
If force is applied to the side of the speaker, it may
fall and damage the speaker or cause personal
injury. Please be careful.
