Your Optimus CD-3620/CD-3640 Portable Compact Disc Player is an example of
superior design and craftsmanship.  The following suggestions will help you
care for your CD player so you can enjoy it for years.

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

    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.

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

    Handle the CD player gently and carefully.  Dropping it can damage
    circuit boards and cases and can cause the CD player to work improperly.

    Use only fresh batteries of the requires size and type.  Old batteries
    can leak chemicals that damage your CD player's electronic 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.

Modifying or tampering with the CD player's internal components can cause
a malfunction and might invalidate your 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 RadioShack store for assistance.

CD CARE TIPS

    Do not place anything but a CD in the disc tray.  Doing so can damage 
    the drive mechanism.

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

    Always handle a CD by the edges and 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 CD cleaner kit (Cat. No. 42-226).

    A scratch on the CD's surface can make the CD skip or stop playing.  If
    the CD gets scratched, use Scratch 'n Fix (Cat. No. 42-127) to repair
    the scratch.

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