Your Optimus CD-3680/CD-3690 Portable Compact Disc Player with Digital Anti- Shock is an example of superior design and craftsmanship. The following sugges- tions 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 environ- ments. Temperature extremes can shorten the life of electronic de- vices, damage batteries, and distort or melt plastic parts.

Keep the CD player away from dust and dirt, which can cause prema- ture 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 im- properly.

Use only fresh batteries of the required size and type. 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 deter- gents to clean the CD player.

Modifying or tampering with the CD player’s internal components can cause a mal- function and might invalidate your CD player’s warranty and void your FCC authori- zation to operate it. If your CD player is not performing as it should, take it to your local RadioShack store for assistance.
