MICRO-21 (140-1159) Maintenance Faxback Doc. # 7220 Your Radio Shack MICRO-21 Microcassette Recorder is an example of superior design and craftsmanship. The following suggestions will help you care for the recorder so you can enjoy it for years. Keep the recorder dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Handle the recorder gently and carefully. Dropping it can damage the circuit boards and case and can cause the recorder to work improperly. Use and store the recorder only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts. Keep the recorder away from dust and dirt, which can cause premature wear of parts. Wipe the recorder with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the recorder. Use only fresh batteries of the recommended size and type. To prevent damage form leakage, always remove dead or weak batteries. Modifying or tampering with the recorder's internal parts can cause a malfunction and might invalidate your recorder's warranty. If your recorder is not operating as it should, take it to your local Radio Shack store for assistance. Cleaning the Tape-Handling Parts Clean the tape-handling parts after about every 20 hours of use. With power supplied and the cassette removed, press PLAY to expose the tape-handling parts. Use a cotton swab dipped in tape head cleaning solution or denatured alcohol to gently clean the parts shown in the illustration. After you finish cleaning the tape-handling parts, press STOP to turn off the recorder and release the tape-handling parts. NOTE: For easier cleaning, use Radio Shack's microcassette cleaner kit (Cat. No. 44-1168), which includes a special cleaning cassette. (ALL-9/15/94)
