PRO LX7 Bookshelf Speaker (400-4063) Care and Maintenance Faxback Doc. # 32909 Your Optimus PRO LX7 Bookshelf Speaker is an example of superior design and craftsmanship. The following suggestions will help you care for your speaker so you can enjoy it for years. Keep the speaker dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits. Use and store the speaker only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts. Keep the speaker away from dust and dirt, which can cause premature wear of parts. Handle the speaker gently and carefully. Dropping it can damage circuit boards and cases and can cause the speaker to work improperly. Wipe the speaker with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the speaker. CAUTION: You might permanently damage your speaker by cleaning it with a vacuum cleaner. Instead, use a feather duster or a soft cloth. Modifying or tampering with the speaker's internal components can cause a malfunction and might invalidate your speaker's warranty. If your speaker is not performing as it should, take it to your local Radio Shack store for assistance. (BR/EB 5/6/96)
