MMS-20 (250-1109) Care and Maintenance Faxback Doc. # 3305 The Radio Shack MMS-20 Multimedia Amplified Speaker System is an example of the finest design and craftsmanship. The following suggestions will help you care for your speaker system so you can enjoy it for years. Never leave the MMS-20 in contact with rubber or vinyl for an extended period of time. The rubber or vinyl might stick to the surface and damage the cabinet. Keep the MMS-20 dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that corrode electronic circuits. Use and store the MMS-20 only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts. Handle the MMS-20 gently and carefully. Dropping it can damage circuit boards and cases and can cause the MMS-20 to work improperly. Keep the MMS-20 away from dust and dirt, which can cause premature wear of parts. Wipe the MMS-20 with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean your MMS-20. Modifying or tampering with the MMS-20's internal components can cause a malfunction and invalidate your MMS-20's warranty. If your MMS-20 is not performing as it should, take it to your local Radio Shack store for assistance. (br/all-11/3/94)
