DeutschFrancais EspanolEnglish E-1 Precautions When Positioning the Speakers Precautions When Positioning the Speakers ¦ 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.
