(120-2152) Care and Maintenance Faxback Doc. # 37647
Your Optimus High-Power in-Dash AM/FM Stereo CD Player is an example of
superior design and craftsmanship. The following suggestions will help
you care for the stereo so you can enjoy it for years.
Keep the stereo dry. If it gets wet, wipe it dry immediately.
Liquids can contain minerals that can corrode electronic circuits.
Handle the stereo gently and carefully. Dropping it can damage the
circuit boards and case and can cause it to work improperly.
Keep the stereo away from dust and dirt, which can cause premature
wear of parts.
Wipe the stereo with a damp cloth occasionally to keep it looking new.
Do not use harsh chemicals, cleaning solvents, or strong detergents to
clean the stereo.
Modifying or tampering with the stereo's internal parts can cause a
malfunction and might invalidate your stereo's warranty and void your FCC
authorization to operate it. If your stereo is not performing as it
should, take it to your local Radio Shack store for assistance.
CD CARE TIPS

recommend the following precautions.
Keep the CD in its protective case or sleeve when you are not playing

CD player's laser beam from accurately reading the CD. Your local
Radio Shack store sells a suitable CD cleaner kit.
Do not write on either side of the CD, particularly the non-label
side. (Signals are read from the non-label side.)
Keep the CD dry. A water drop can act as a lens and affect the laser
beam's focus.
