– Use the required tools to install the device.

 

– Inspect the device periodically.

 

• 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.

 

• Do not insert your fingers or hands in any gaps or openings 

on the device (ports).

 

• Avoid inserting or dropping foreign objects (paper, plastic,

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.

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.

The woofer employs a material for the surround to achieve high sound 
quality. The useful life of the speaker surround depends on usage conditions 
and environment (especially ultraviolet radiation exposure and humidity), 
etc. When the speaker surround reaches the end of its useful life, refer to your 
dealer for replacement.

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")

 

•

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.
