PRO LX5 Speaker (400-4061) Care and Maintenance Faxback Doc. # 15844 Your Optimus PRO LX5 5-Inch 2-Way Metal Cabinet 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 can contain minerals that can corrode the electronic circuits. Handle the speaker gently and carefully. Dropping it can damage circuit boards and cases and cause the speaker to work improperly. 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. 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. Modifying or tampering with the speaker's internal components can cause a malfunction and might invalidate the speaker's warranty. If your speaker is not performing as it should, take it to your local Radio Shack store for assistance. The upper diaphragm on this speaker is not user-cleanable. It must be sent to a service center for cleaning. Any attempt on the user's part to clean this would probably result in damage to the speaker.
