Precaution on use

■Placement

•The enclosure is made of wood and therefore sensitive to extreme temperatures and humidity. Avoid placing the unit in locations subjected to direct sunlight or in humid places such as near an air conditioner, bathroom or kitchen, as well as in locations subjected to soot or steam such as near a kitchen table and humidifier. Otherwise, damage may occur.

•Keep water or other liquids away from the unit. If water is spilled into the unit, not only the unit but also the connected amplifier (receiver) may be damaged.

•Place the unit on a level and rigid surface free from vibration.

•Slip-proof spacers are provided with the SL-105. If the SL- 105 is to be placed on flooring or other similar surfaces, attach these spacers to the bottom surface at the corners. This will not only prevent scratching, but also provide a stable footing. However, note that depending on the surface, the spacers may leave markings.

•This unit is designed to be used in the upright vertical position only. Do not use it in the horizontal or tilted position.

•If the unit is used near a turntable or CD player, howling or skipping of sound may occur. To prevent this, move the unit away from the turntable or CD player or otherwise lower the unit’s output level.

•This unit can handle the specified input power when it is used for ordinary music reproduction. If the following abnormal signals are fed to the unit, however, an overcurrent may flow in the internal circuits, causing burning or breakage of the wires even if the input power is below the specified rating.

1.Special test signals produced by audio checking CD, etc.2.Sound produced when connecting or disconnecting audio connection cables.

(Always turn off the amplifier’s power before connecting or disconnecting cables.)

3.Howling when a microphone is used.

4.Abnormal sound produced when bass-range signals are excessively boosted by using the amplifier’s (receiver’s) tone controls, a graphic equalizer, etc., or when a source whose bass range is abnormally boosted is being played. This state called “rattling” occurs when the signal is beyond the driver’s reproduction capacity. Although it is not a sign of damage, decrease the speaker output level to prevent damage to the driver.
