CTR-26 Cassette Tape Recorder (140-0823) Care and Maintenance Faxback Doc. # 18766 With batteries and cassette removed, and with cassette lid up, press down the PLAY key, exposing the erase and record heads and the rubber drive wheel. Clean these points, using a cotton swab moistened with denatured alcohol (not rubbing alcohol) or with a special head cleaning fluid. Your Radio Shack store has these items. To insure good recording and playback results, clean after first 6, 18, and 40 hours of use. Further cleaning should be required only after each additional 40 hours of operation. After cleaning, be sure to press the STOP key, so that these parts may return to their normal operating position for cassette loading. For easy cleaning, we recommend our Cassette Head Cleaning Cartridge, 44-1160 CAUTION: Do not expose the tape recorder or the cassette to high temperature or high humidity. Do not touch the tape heads with screwdriver or other metal object or any magnetic object. Remove batteries when recorder is not in use for more than a month, because battery leakage may damage the unit. Don't leave weak or dead batteries in the Recorder. (PH 12/6/95)
