STS 50 Two-Way (400-0230) Care and Maintenance Faxback Doc. # 14035 Bookshelf Speaker Your new Optimus STS 50 Two-Way Bookshelf Speaker is an example of superior design and craftsmanship. The following suggestions will help you care for it, so you can enjoy it for years. Keep the speaker enclosure dry. If it gets wet, wipe it dry immediately. Liquids contain minerals that can corrode electronic circuits. Keep the speaker away from dust and dirt which can cause premature wear of parts. Wipe the speaker enclosure occasionally with a cloth dampened with furniture polish. This will help to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents. Caution: You might permanently damage your speaker enclosure's grille or the speaker elements by cleaning them 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 the warranty. If the speaker is not operating as it should, take it to your local Radio Shack store for assistance. (ALL-03/09/95)
