Avoid sources of humming (transformers, motors). To prevent fire or electric shock, do not expose the speakers to dripping or splashing. • To prevent the enclosure from warping or discoloring, do not place the speakers where they will be exposed to direct sunlight or excessive humidity. • Do not place the following objects on top of the speakers: 1. Glass, china, etc. If glass etc. falls by vibrations and breaks, it may cause personal injury. 2. A burning candle etc. If the candle falls by vibrations, it may cause fire and personal injury. 3. A vessel with water in it If the vessel falls by vibrations and water spills, it may cause damage to the unit, and/ or you may get an electric shock. • Do not place the speakers where foreign objects such as water drips might fall. It might cause a fire, damage to this unit, and/or personal injury. • 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. • Secure placement or installation is the owner’s responsibility. Yamaha shall not be liable for any accident caused by improper placement or installation of speakers. • Any time you note distortion, reduce the volume of your amplifier immediately. Make sure the input power does not exceed the specified maximum input power, otherwise the speakers will be damaged. • Do not attempt to clean the speakers with chemical solvents as this might damage the finish. Use a clean, dry cloth. • Do not attempt to modify or fix the speakers. Contact qualified Yamaha service personnel when any service is needed. The cabinet should never be opened for any reasons.

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.). Placing the Speakers Place the speakers on a sturdy, vibration-free surface. ¦ Using as Normal Stereo Speakers To get the best stereo performance, angle the speakers inward so as to create a triangle, with the listener at the apex. ¦ Using as Front Speakers in a Surround Sound System Position the speakers both side of your TV. The positioning of these speakers is important because they provide a solid anchor for the sound image. They should be positioned facing the listener at about ear level, and equidistant from the TV.
