Operation to reset
The microcomputer may fall into malfunction (impossibility to operate, erroneous display, etc.) when the power cord is unplugged while power is ON or due to an external factor. In this case, execute the following procedure to reset the microcomputer and return it to normal condition.
¶ Please note that resetting the microcomputer clears the contents stored in it returns it to condition when it left the factory.
Unplug the power cord from the AC outlet and, while 0 holding the "0eject" key depressed, plug the power cord again.
¶ If a tape is loaded in the deck, it will be ejected now.
DISASSEMBLY FOR REPAIR
ELECTRIC CHECK
1) Remove insulator a'ssy, then remove some screw of L,R side board(1). Next remove the top and the bottom boards, then remove the power transformer and the rear panel assembling PCB. 2) Connect GND between PCB and the deck mechanism with a alligator clip lead weir (2).

CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list). indicates safety critical components. For continued protection against risk of fire, replace only with same type and rating fuse(s). 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.
The DC voltage is an actual reading measured with a high impedance type voltmeter with a cassette loaded at playback mode. The measurement value may vary depending on the measuring instruments used or on the product. Bias circuit DC voltage is measured while in the record mode.
