JBL Synthesis Everest DD67000 - Manual (Page 23)

Project Everest loudspeakers require no maintenance other than occasional dusting with
a soft, dry, lint-free cotton cloth. The horns may also be wiped with a soft cloth. Treat the
lacquered surface very carefully to avoid scratching the finish. To remove fingerprints and
smudges, apply a small amount of diluted ammonia-free or alcohol-free neutral detergent
to the cloth and gently clean the surface.
• Never use any abrasive cleaners or chemicals to clean the enclosure. If the enclosure
becomes noticeably scratched or otherwise damaged, consult a qualified furniture
repair shop.
• 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.
• If the surfaces of the low-frequency driver cones become dusty, you can carefully
sweep them clean with a soft, dry calligraphy brush or paint brush. Do not use a
damp cloth.
All wiring connections should be inspected and cleaned or remade periodically.
The frequency of maintenance depends on the metals involved in the connections,
atmospheric conditions, and other factors. Consult your Project Everest dealer for specific
recommendations.
trouBLeshootinG and service Guide
Project Everest loudspeakers are designed to provide years of trouble-free service.
No maintenance is required.
If a problem occurs, make sure that all connections are properly made and clean. If a
problem exists in one loudspeaker, reverse the speaker wires to the left and right speakers.
If the problem appears in the opposite speaker, the cause is in another component or
cable. If the problem remains in the same speaker, then the fault is in the loudspeaker. In
this event, consult your Project Everest dealer for assistance.
