JBL 4318 - Manual (Page 3)

The speakers are shipped with the grill installed.
The purpose of the grill is to protect the units. The grill may be removed and re-attached as necessary.
7: Maintenance
• When doing any maintenance, wipe the surface of the cabinet with a dry cloth to remove dust. Damp cloth or cleaning
paper may dull the finish on the cabinet surface. Do not use volatile liquids such as benzene, paint thinner, alcohol, etc,
and do not spray insecticide near it.
• If dust gets into the grill netting, use a vacuum cleaner to remove it. In doing so, adjust the suction power of the
vacuum cleaner so that it does not suction too strongly. Furthermore, do not wash the grill in water. The grill may sag
or its color may become uneven.
• If the surface of the speaker unit becomes dusty, use a soft, dry calligraphy brush or a paint brush to carefully sweep the
dust away. Never use a damp cloth.
•The speaker system is a durable consumer good. In particular, the edges of the woofer, which support rapid movement
of the paper cone, undergo a great level of stress, and there is a limit to the number of years of its practical use. Also,
the speakers' lifespan may be shortened by the effects of temperature, humidity or ultra-violet radiation. Please avoid
exposing the speaker to strong lighting such as from lighting equipment or direct sunlight and avoid placing the
speakers in high temperatures such as near the air conditioner exhaust pipe or a heat radiator.
