Maintenance When the unit gets dirty, wipe it with a soft dry cloth. If heavily contaminated, wipe it with a soft cloth soaked with mild soapy water and then wipe with a dry cloth. Never use alcohol, thinner, benzine or other volatile agent since the painting may be damaged. Head Cleaning * Drop out, degradation of frequency characteristic or wow & flutter may be caused when the recording/playback head, capstan and roller get dirty with magnetic material powder or dust. Clean these parts from time to time so as to enjoy perfect tape sound reproduction. Before cleaning, open the CASSETTE COMPARTMENT door. Use a cotton swab slightly wetted with diluted anhydrous alcohol and clean the recording/playback head, erasing head, capstan and roller which come into direct contact with the tape. Do not wet the cotton swab with too much alochol. Tape playback shall be started after thorough evaporation of alcohol. ® The recording/playback head, erasing head and capstan will be magnetized gradually. Since the magnetism causes noise generation and degradation of high-frequency range characteristic, be sure to demagnetize these parts with a head eraser. 13
