Caring For Your Speakers - Harman JBL S3900 El Manual Del Propietario

CARINg FOR YOUR SPEAkERS

Wipe the cabinet with a clean, dry cloth to remove dust. A damp cloth may dull the cabinet's finish. Do not use volatile
liquids such as benzene, paint thinner or alcohol on the cabinet.
• Do not spray insecticide near the cabinet.
• To remove dust from the grille fabric, use a vacuum cleaner set to low suction.
• Do not wash the grille in water, as water may fade the grille's color or make it uneven.
• Never apply suction or pressurized air to the high-frequency or ultrahigh-frequency horn openings.
• If the surface of the low-frequency driver cone becomes dusty, you can carefully sweep it clean with a soft, dry
calligraphy brush or paint brush. Do not use a damp cloth.
• The grille only fits on the speaker one way, so if you remove the grille, please note the proper orientation of the grille
pins before re-installing the grille on the speaker.
