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, humidifier, a
bathroom or kitchen. If you do so, damage may occur.
• Keep water and other liquids away from the unit. If water is spilled into the unit, not only the unit but also the
connected receiver may be damaged.
• Place the unit on a level and rigid surface free from vibration.
• 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.
Note:
Abnormal sound can be produced when bass-range signals are excessively boosted by using the receiver’s tone controls
or a graphic equalizer, or when a source has the bass range abnormally boosted and is played. 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.
