1) During FWD transport adjust (F) and (F') so that line A of 2-LINE TAPE passes trough the center of the head shield plate (core center area) 2) During RVS transport adjust screws (R) and (R') Head Height so that line B of 2-LINE TAPE passes trough the TAPE PLAY center of the head shield plate (core center area) Screw 3) After the alignment above, reverse the transport direction and check the FWD alignment again. If it is deviated, perform alignment again. (Tape used : SCC-1659, manufactured by A-BEX)

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list). ! Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer. · DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
