These precautions include, but are not limited to, the
following:
Location
Do not place the device in an unstable position where it
might accidentally fall over.
Do not block the vents. This device has a port at the bottom
to prevent the internal temperature from becoming too high.
In particular, do not place the device on its side or upside
down. Inadequate ventilation can result in overheating,
possibly causing damage to the device(s), or even fire.
When installing the device:
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.
Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), or even fire.
Do not press the rear panel of the device against the wall.
Doing so may cause the plug to come in contact with the
wall and detach from the speaker cable, resulting in short
circuiting, malfunction, or even fire.
Do not place the device 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 device during a disaster, such as an
earthquake. Since the device may fall and cause injury, stay
away from the device quickly and move to a safe place.
Before moving the device, remove all connected cables.
When transporting or moving the device, always use two or
more people. Attempting to lift the device by yourself may
damage your back, result in other injury, or cause damage to
the device itself.
If you are not a qualified service technician, do not attempt to
install the device. Always consult qualified Yamaha service
personnel if the device installation requires construction
work, and make sure to observe the following precautions.
Choose mounting hardware and an installation location
that can support the weight of the device.
Avoid locations that are exposed to constant vibration.
Use the required tools to install the device.
Inspect the device periodically.
Connections
Before connecting the device to other devices, turn off the
power for all devices. Before turning the power on or off for
all devices, set all volume levels to minimum.
Use only speaker cables for connecting speakers to the
speaker jacks. Use of other types of cables may result in fire.
Handling caution
Do not insert your fingers or hands in any gaps or openings
on the device (ports).
Avoid inserting or dropping foreign objects (paper, plastic,
metal, etc.) into any gaps or openings on the device (ports)
If this happens, turn off the power of external devices
immediately and unplug the power cord from the AC outlet.
Then have the device inspected by qualified Yamaha service
personnel.
Do not rest your weight on the device or place heavy objects
on it, and avoid use excessive force on the buttons, switches
or connectors.
Do not use the speakers 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.
Do not operate the device if the sound is distorting.
Prolonged use in this condition could cause overheating and
result in fire.
When choosing a power amplifier for use with this device,
make sure that the output power of the amplifier is lower
than the power capacity of this device. If the output power
is higher than the power capacity, malfunction or fire may
occur.
Do not input excessively loud signals that may result in
clipping in the amplifier or cause the following:
Feedback, when using a microphone
Continuous and extremely loud sound from a musical
instrument, etc.
Continuous and extremely loud distorted sound
Noise caused by plugging/unplugging the cable while the
amplifier is turned on
Even if the output power of the amplifier is lower than the
power capacity of this device (program), damage to the
device, malfunction or fire may occur.
Yamaha cannot be held responsible for damage caused by
improper use or modifications to the device.
Notice
To avoid the possibility of malfunction/ damage to the product,
damage to data, or damage to other property, follow the notices
below.
Handling and maintenance
Do not expose the device to excessive dust or vibration, or
extreme cold or heat (such as in direct sunlight, near a heater,
or in a car during the day), in order to prevent the possibility
of panel disfiguration, unstable operation, or damage to the
internal components.
Do not place vinyl, plastic or rubber objects on the device,
since this might discolor the panel.
When cleaning the device, use a dry and soft cloth. Do not
use paint thinners, solvents, cleaning fluids, or chemical-
impregnated wiping cloths.
During extreme changes in temperature or humidity,
condensation may occur and water may collect on the surface
of the device. If water is left, the wooden parts may absorb
the water and be damaged. Make sure to wipe any water off
immediately with a soft cloth.
Be sure to observe the amplifier’s rated load impedance,
particularly when connecting speakers in parallel. Connecting
an impedance load outside the amplifier's rated range can
damage the amplifier.
Protective Circuit (poly switch)
All full-range loudspeakers are fitted with a self-resetting
poly switch that protects the high-frequency driver from
damage caused by excessive power. If a loudspeaker cabinet
loses high-frequency output, immediately remove power
from the unit and wait for two to three minutes. This should
be long enough to allow the poly switch to reset. Reapply
power and check the performance of the high-frequency
driver before continuing, with the power reduced to a level
that does not cause the poly switch to interrupt the signal.
Air blowing out of the bass reflex ports is normal, and often
occurs when the speaker is handling program material with
heavy bass content.

Specifications

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.
To fix the speaker to a mounting bracket, use the screws inserted to the screw
holes of the speaker as the factory default status. If you use the commercially
available screws, use the screws that matches to the following specifications:
Screw type ............................................. M8
Screw length ..........35 mm (1 3/8") or more 100 mm (3 15/16")
Caution
The required length of a screw differs depending on the mounting bracket to
be used. Select a screw which is suitable for use with the mounting bracket
and can be fully inserted into the hole on the speaker.
As this product is heavy, do not attach them to thin plywoods or soft wall
surface materials, as the screws may tear free from flimsy surfaces, causing
the speaker to fall and be damaged, or result in personal injury.
Do not fasten the speaker to the ceiling with nails, adhesives, or other
unsound hardware. Long-term use and vibrations may cause them to pull
free.
To avoid accidents resulting from tripping over loose speaker cables, fix
these to the wall along with the speaker.
