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 the chassis. Any current measured must not exceed 0.5mA. Reverse the instrument power cord plug in the outlet and repeat the test. See Fig. 1-1. Any measurements not within the limits specified herein indicate a potential shock hazard that must be eliminated before returning the instrument to the customer. (READING SHOULD NOT BE ABOVE 0.5mA) DEVICE UNDER TEST TEST ALL EXPOSED METER SURFACES 2-WIRE CORD ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) EARTH GROUND LEAKAGE CURRENT TESTER Fig. 1-1 AC Leakage Test (4) Insulation Resistance Test Cold Check-(1) Unplug the power supply cord and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the instrument. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and all exposed metallic cabinet parts on the instrument, such as screwheads, antenna, control shafts, handle brackets, etc. When an exposed metallic part has a return path to the chassis, the reading should be between 1 and 5.2 megohm.

Set the Oscilloscope Range as follows : (Voltage ; 20mV/Div., Frequency ; 10m Sec.) 3) Adjust the Screws "A" and "B" (See Fig. 2-2) using a Hex screwdriver until you obtain a Flat Waveform and the picture is stable. Then, go to Chapter 1 and make sure the Waveform is Flat here as well. If not, you have to go back to Chapter 14 and adjust again. If you cannot obtain a Flat waveform, then the unit is defective. Note : The Deck must be in a horizontal position. Use both "A" and "B" screws to adjust.

Set the Oscilloscope Range as follows : (Voltage ; 20mV/Div., Frequency ; 10m Sec.) 3) Adjust the Screws "A" and "B" (See Fig. 6-2) using a Hex screwdriver until you obtain a Flat Waveform and the picture is stable. Then, go to Chapter 1 and make sure the Waveform is Flat here as well. If not, you have to go back to Chapter 14 and adjust again. If you cannot obtain a Flat waveform, then the unit is defective. Note : The Deck must be in a horizontal position. Use both "A" and "B" screws to adjust.

High inverted power occurs at switch (PQR11) off, because of the 1st winding of transformer : (V=-L1 xdi/dt. L1 : Leakage Induction) A very high residual voltage exist on both terminals of PQR11 because dt is a very short. 2) SNUBBER circuit protects PQR11 from damage through leakage voltage suppression by RC, (Charges the leakage voltage to PDS11, PER13, PCD12 and discharges to PRS13). 0 Toff t Fig. 7-7 7-1-2 (c) Driving circuit When Vin supplied, driving current Ig occurs throuhg the PRR11.
