IMPORTANT SERVICE GUIDE MODE SWITCH (PROGRAM SWITCH) ASSEMBLY POINT 1) When installing the ass'y deck on the Main PCB, be sure to align the assembly point of mode switch. ASSEMBLY POINT MAIN PCB Fig. 1 HOW TO EJECT THE CASSETTE TAPE (If the tape is stuck in the unit) 1) Turn the Gear Worm OE clockwise in the direction of arrow with screwdriver. (See Fig. 2) (Other method ; Remove the screw of Motor Load Ass'y, Separate the Motor Load Ass'y) 2) When Slider S, T are approach the unloading position, rotate holder Clutch counterclockwise after inserting screwdriver in the frame's bottom hole in order to wind the unwound tape. (Refer to Fig. 3) (If you rotate Gear Worm OE continuously when tape is in state of unwinding, you may cause tape contamination by grease and tape damage. Be sure to wind the unwound tape in the state of set horizontally.) 3) Rotate Gear Worm OE clockwise using screw driver again up to the state of eject mode and then pick out the tape. (Refer to Fig. 2) OE GEAR WORM FRAME Fig. 2 Fig. 3 1. Precautions 1-1 Safety Precautions 1) Before returning an instrument to the customer, always make a safety check of the entire instrument, including, but not limited to, the following items: (1) Be sure that no built-in protective devices are defective or have been defeated during servicing. (1)Protective shields are provided to protect both the technician and the customer. Correctly replace all missing protective shields, including any removed for servicing convenience. (2)When reinstalling the chassis and/or other assembly in the cabinet, be sure to put back in place all protective devices, including, but not limited to, nonmetallic control knobs, insulating fish papers, adjustment and compartment covers/shields, and isolation resistor/capacitor networks. Do not operate this instrument or permit it to be operated without all protective devices correctly installed and functioning. (2) Be sure that there are no cabinet openings through which adults or children might be able to insert their fingers and contact a hazardous voltage. Such openings include, but are not limited to, excessively wide cabinet ventilation slots, and an improperly fitted and/or incorrectly secured cabinet back cover. (3) Leakage Current Hot Check-With the instrument completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards institute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL) 1270 (40.7). With the instrument's AC switch first in the ON position and then in the OFF position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle brackets, metal cabinets, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to
