AM/FM Cassette Player (120-2101) Maintenance Faxback Doc. # 7322 CARING FOR THE STEREO The Optimus AM/FM Stereo Car Cassette Player is an example of superior design and craftsmanship. The following suggestions will help you care for the stereo so you can enjoy it for years. Keep the stereo dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode electronic circuits. Handle the stereo gently and carefully. Dropping it can damage the circuit boards and case and can cause it to work improperly. Keep the stereo away from dust and dirt, which can cause premature wear of parts. Wipe the stereo with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the stereo. Modifying or tampering with the stereo's internal parts can cause a malfunction and might invalidate the stereo's warranty and void your FCC authorization to operate it. If your stereo is not operating as it should, take it to your local Radio Shack store for assistance. THE FCC WANTS YOU TO KNOW Your stereo might cause TV or radio interference even when it is operating properly. To determine whether the stereo is causing the interference, turn off the stereo. If the interference goes away, the stereo is causing the interference. Try to eliminate the interference by: Moving the stereo away from the receiver. Contacting your local Radio Shack store for help. If you cannot eliminate the interference, the FCC requires that you stop using the stereo. CLEANING THE TAPE-HANDLING PARTS Clean the tape head after every 20 hours of playing time. Insert a special head-cleaning cassette (such as Cat. No. 44-1162), and let it run for a few minutes to remove any foreign matter. REPLACING A FUSE If the stereo does not work, you might need to replace the red power wire's fuse. If the clock resets or stored stations are lost when the ignition is off, you might need to replace the yellow continuous power wire's fuse. Warning: Before you begin, turn off the stereo and your vehicle's ignition. 1. Disconnect the red and yellow power wires. 2. Push together and twist the fuse holder's parts until they spring apart. 3. If the fuse is blown, replace it . Use only standard 1 1/4-inch fuses with the proper rating. The red power wire's fuse must be 3.0 amps, and the yellow continuous power wire's fuse must be 0.5 amp. 4. Reassemble the fuse holder by inserting the fuse and pushing together and twisting the two parts until they snap together. 5. Reconnect the red and yellow power wires. (br/all-8/11/94)
