CD CARE

This CD player has a wide dynamic range.  If you turn up your amplifier's
volume too high during soft (low volume) parts of the music, you might
damage your speakers when a sudden loud passage occurs.

During play, a severe shock or jolt could make the CD's rotation speed
change suddenly and produce some noise.  This is not a malfunction.

If you move the player from a very cold room to a warmer one, moisture can
condense on the pickup lens, preventing proper disc play.  If this happens,
wait 30 minutes before resuming play.

Do not place foreign objects in the CD compartment.  This can damage the
drive mechanism.

Treat the CD surface with care.  Always handle a CD by the edges to avoid
fingerprints and always keep it in its protective case or sleeve when it is
not in use.  Fingerprints and scratches on the CD's surface can prevent the
laser beam from correctly reading the digital information.  To clean the
CD, use a Radio Shack CD Cleaner Kit (Cat. No. 42-226).

A scratch on the CD's surface can make the CD skip or stop playing.  You
can repair most scratches using a Radio Shack Scratch 'n Fix kit (Cat. No.
42-127).

Keep the CD dry.  A water drop can act as a lens and affect the laser
beam focus.

CARING FOR THE CD-3490

The CD-3490 Portable Compact Disc Player is an example of superior design
and craftsmanship.  The following suggestions will help you care for the
CD player so you can enjoy it for years.

    Keep the CD player dry.  If it gets wet, wipe it dry immediately.
    Liquids can contain minerals that corrode the electronic circuits.

    Handle the CD player gently and carefully.  Dropping it can damage the
    circuit board and case, and can cause the player to work improperly.

    Keep the CD player away from dust and dirt, which can cause premature
    wear of parts.

    Wipe the CD player with a damp cloth occasionally to keep it looking
    new.  Do not use harsh chemicals, cleaning solvents, or strong
    detergents to clean the CD player.

    Use and store the CD player only in normal temperature environments.
    Temperature extremes can shorten the life of electronic devices,
    damage batteries, and distort or melt plastic parts.

    Use only fresh batteries of the required size and type.  Always remove
    old or weak batteries.  They can leak chemicals that destroy
    electronic circuits.

Modifying or tampering with the CD player's internal components can cause
a malfunction and might invalidate the CD player's warranty and void your
FCC authorization to operate it.  If your CD player is not performing as
it should, take it to your local Radio Shack store for assistance.
