Care of Your Speakers
Clean your cabinets using a soft, lint-free cloth. If you wish, you can slightly
moisten the cloth with plain water. Do not use any other cleaning agents
or chemicals. Be careful not to get any water on the driver cones or tweeter
domes. After carefully removing the grilles from the speakers by pulling
them forward, gently clean them with a quick pass from a vacuum cleaner
with a brush attachment. This should remove any dust accumulation. Reat-
tach them by lining up the magnet depressions in the back of the grilles with
the magnets on the speaker baffle and slowly moving them closer until they
connect with each other.
Optional Accent Panel Kits are available to dress up your speaker system.
These kits are available in three different vinyl finishes to compliment any
décor. Please contact your Atlantic Technology dealer for further details.
Avoid placing your speakers in direct sunlight or near a source of heat that
may, over time, damage the finish.
IMPORTANT: SAVE YOUR BOXES!
If you can do so, save the car-
tons, packing pieces, and plastic bags that came with your speakers.
They will be useful in case you move or have to ship your loudspeak-
ers for any reason. In any case, save all packing materials until you
are certain that the systems have suffered no damage in shipment. If
you find such damage, either visible or internal, contact your dealer
immediately.
