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

  Keep the CD-3640 dry.  If it gets wet, wipe it dry immediately.  Liquids
  might contain minerals that can corrode the electronic circuits.

  Use and store the CD-3640 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-3640 away from dust and dirt, which can cause premature wear
  of parts.

  Handle the CD-3640 gently and carefully.  Dropping it can damage circuit
  boards and cases and can cause the CD-3640 to work improperly.

  Use only fresh batteries of the required size and recommended type.
  Batteries can leak chemicals that damage your CD-3640's electronic
  parts.

  Wipe the CD-3640 with a damp cloth occasionally to keep it looking new.
  Do not use harsh chemicals, cleaning solvents, or strong detergents to
  clean the CD-3640.

Modifying or tampering with the CD-3640's internal components can cause a 
malfunction and might invalidate its warranty.  If your CD-3640 is not 
performing as it should, take it to your local RadioShack store for 
assistance.

Cleaning the Tape Handling Parts

Dirt, dust, or particles of the tape's coating can accumulate on the tape 
heads and other parts that the tape touches.  This can greatly reduce the 
performance of the cassette player.  After every 20 hours of tape player 
operation, follow these steps to clean the tape-handling parts or use a 
RadioShack cassette deck cleaning kit.

1.  Remove the batteries and disconnect any other power source.

2.  Open the cassette compartment door.

3.  With the eraser end of a pencil, gently press down on the erase
    protection sensor.

4.  While holding down the erase-protection tab sensor, press RECORD to
    expose the tape-handling parts.

5.  Use a cotton swab in denatured alcohol or tape head cleaning solution
    to clean the tape guides, record/play head, erase head, pinch roller,
    and capstan.

6.  When you finish cleaning, press STOP/EJECT and close the cassette
    compartment door.  Then reconnect power.
