Notes

CLEANING
NOTE After cleaning the heads with isopropyl alcohol, do not run a tape until the heads dry completely. If the heads are not completely dry and alcohol gets on the tape, damage may occur. 1. AUDIO CONTROL HEAD Clean the Audio Control Head with the cotton stick soaked by alcohol. Clean the full erase head in the same manner. (Refer to the figure below.) 2. TAPE RUNNING SYSTEM When cleaning the tape transport system, use the gauze moistened with isopropyl alcohol. 3. CYLINDER Wrap a piece of chamois around your finger. Dip it in isopropyl alcohol. Hold it to the cylinder head softly. Turn the cylinder head counterclockwise to clean it (in the direction of the arrow). (Refer to the figure below.) NOTE Do not exert force against the cylinder head. Do not move the chamois upward or downward on the head. Use the chamois one by one.
