• 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.

• 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.

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.

• 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.
You can also use the screw holes on the top of the speaker for installing the
speaker on the ceiling by using commercially available mounting brackets.
