For continued safety replace safety critical components only with manufactures recommended parts. Type No indication MM PP MPP MF TF BP TAN (3)Coils No unit : Original setting position when shipped :DC 20k :H :V :Others (5)Voltage values /V 20µs/div 5ms/div Sweeping time is specified Others (4)Power Supply :B1 :9V Respective voltage values are indicated (5)Test point :Test point (6)Connecting method :Connector :Wrapping or soldering :Only test point display :B2 (12V) :5V :[ µ H] :As specified :Ceramic capacitor :Metalized mylar capacitor :Polypropylene capacitor :Metalized polypropylene capacitor :Metalized film capacitor :Thin film capacitor :Bipolar electrolytic capacitor :Tantalum capacitor 2.SPECIFIED VOLTAGE AND WAVEFORM VALUES The voltage and waveform values have been measured under the following conditions. (1)Input signal (2)Setting positions of each knob/button and variable resistor (3)Internal resistance of tester (4)Oscilloscope sweeping time : Colour bar signal :All DC voltage values Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values. 3.INDICATION OF PARTS SYMBOL [EXAMPLE] In the PW board :R1209 R209 (7)Ground symbol :LIVE side ground :ISOLATED(NEUTRAL) side ground :[ :[ k :[M ] ] ] :EARTH ground :DIGITAL ground :Receptacle 4.INDICATIONS ON THE CIRCUIT DIAGRAM (1)Resistors Resistance value No unit K M Rated allowable power No indication :1/ 16 [W] Others Type No indication OMR MFR MPR UNFR FR (2)Capacitors Capacitance value 1 or higher less than 1 Withstand voltage No indication Others :[pF] :[µF] :DC50[V] :DC withstand voltage [V] :Carbon resistor :Oxide metal film resistor :Metal film resistor :Metal plate resistor :Uninflammable resistor :Fusible resistor :As specified 5.NOTE FOR REPAIRING SERVICE This model's power circuit is partly different in the GND. The difference of the GND is shown by the LIVE : ( ) side GND and the ISOLATED(NEUTRAL) : ( ) side GND.Therefore, care must be taken for the following points. (1)Do not touch the LIVE side GND or the LIVE side GND and the ISOLATED(NEUTRAL) side GND simultaneously. If the above caution is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the receptacle when, for example, the chassis is pulled out. (2)Do not short between the LIV |
