Thank you for selecting a YAMAHA speaker system.

Read these precautions carefully before using your 
speakers.

• 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, small metallic, etc. 

If glass etc. falls by vibrations and breaks, it may 
cause bodily injury. 

A burning candle etc.

If the candle falls by vibrations, it may cause fire and 
bodily 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 bodily 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 bodily 
injury and/or damage to the speaker.

• When moving the speaker, do not hold the port as it 

might cause bodily 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.

• Secure placement or installation is the owner’s 

responsibility. YAMAHA shall not be liable for any 
accident caused by improper placement or 
installation of 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.
