Please read the following operating precautions before use. Yamaha will not be held responsible for any damage and/or 
injury caused by not following the cautions below.

1.

To assure the finest performance, please read this 
manual carefully. Keep it in a safe place for future 
reference.

2.

Install the speakers in a cool, dry, clean place – away 
from windows, sources of heat, sources of excessive 
vibration, dust, moisture or cold. Avoid sources of 
electrical humming (e.g., transformers and motors). To 
prevent fire or electric shock, do not expose the 
speakers to rain or water. 

3.

To prevent the enclosure from warping or discoloring, 
do not expose the speakers to direct sunlight or 
excessive humidity.

4.

Avoid installing the speakers where foreign objects may 
fall onto them and/or where they may be exposed to 
liquid dripping or splashing. 

5.

Do not place the following objects on top of the 
speakers:

– Other components, as they might damage or discolor 

the surface of the speakers.

– Burning objects (e.g., candles), as they might cause 

fire, damage to the speakers or personal injury. 

– Containers of liquid, as they might spill and cause 

electric shock to the user or damage to the speakers.

6.

Do not place the speakers where they are liable to be 
knocked over or struck by falling objects. Stable 
placement will also ensure better sound performance.

7.

Placing the speakers on the same shelf or rack as the 
turntable can result in feedback.

8.

Do not insert a hand or object into the port or pick up 
the speaker by holding the port, as it may cause 
personal injury or damage to the speaker.

9.

Any time you note distortion, reduce the volume control 
on your amplifier to lower setting. Never allow your 
amplifier to be driven into “clipping”. Otherwise, the 
speakers may be damaged.

10.

When using an amplifier with a rated output power 
higher than the nominal input power of the speakers, 
care should be taken not to exceed the maximum input 
of the speakers.

11.

Do not attempt to clean the speakers with chemical 
solvents as this might damage the finish. Use a clean, 
dry cloth.

12.

Do not attempt to modify or fix the speakers. Contact 
qualified Yamaha service personnel when service is 
needed. The cabinet should never be opened for any 
reason.

13. Secure placement or installation is the owner’s 

responsibility. Yamaha is not liable for accidents 
caused by improper placement or installation of 
speakers.

Taking care of the speaker

When you wipe this unit, do not use chemical solvents 
(e.g., alcohol or thinners, etc.): this might damage the 
finish. Use a clean, dry cloth. For difficult soils, 
dampen a soft cloth in water, wring it out, and then 
wipe with the cloth.
(For polish-finished model) Bumping the surface of the 
instrument with metal, porcelain, or other hard objects 
can cause the finish to crack or peel.
