Installation Location
Make sure the CDA-7990 will not be installed
in a location subjected to:
• Direct sun and heat
• High humidity and water
• Excessive dust
• Excessive vibrations
Handling the Detachable Front Panel
• Do not expose to rain or water.
• Do not drop or apply shock.
Correct Handling
Do not drop the disc while handling. Hold the
disc so you will not leave fingerprints on the
surface. Do not affix tape, paper, or gummed
labels to the disc. Do not write on the disc.
Disc Cleaning
Fingerprints, dust, or soil on the surface of the
disc could cause the CD player to skip. For
routine cleaning, wipe the playing surface with
a clean, soft cloth from the center of the disc to
the outer edge. If the surface is heavily soiled,
dampen a clean, soft cloth in a solution of mild
neutral detergent before cleaning the disc.
Disc Accessories
There are various accessories available on the
market for protecting the disc surface and
improving sound quality.
However, most of them will influence the
thickness and/or diameter of the disc. Using
such accessories can cause the disc to be out of
standard specifications and may create
operational problems. We recommend not
using these accessories on discs played in
Alpine CD players.
