2 AV-2CM4/, AV-2CMT4/,AV-24C/E STANDARD CIRCUIT DIARAM NOTE ON USIN CIRCUIT DIARAMS.SAFETY The components identified by the symbol and shading are critical for safety. For continued safety replace safety ciritical components only with manufactures recommended parts. 2.SPECIFIED VOLTAE AND WAVEFORM VALUES The voltage and waveform values have been measured under the following conditions. ()Input signal : Colour bar signal (2)Setting positions of each knob/button and variable resistor 3.INDICATION OF PARTS SYMOL [EAMPLE] In the PW board : R29 R29 : Original setting position when shipped (3)Internal resistance of tester : DC 2kΩ/V (4)Oscilloscope sweeping time : H 2µs / div : V 5ms / div : Othters Sweeping time is specified (5)Voltage values : All DC voltage values Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values. Type No indication MM PP MPP MF TF P TAN (3)Coils No unit Others (4)Power Supply : 9V : Respective voltage values are indicated (5)Test point : Test point : Only test point display (6)Connecting method : Ceramic capacitor : Metalized mylar capacitor : Polypropylene capacitor : Metalized polypropylene capacitor : Metalized film capacitor : Thin film capacitor : ipolar electrolytic capacitor : Tantalum capacitor : [µh] : As specified : : Connector : Wrapping or soldering : Receptacle : 2 (2V) 4.INDICATIONS ON THE CIRCUIT DIARAM ()Resistors Resistance value No unit : [Ω] K : [kω] M : [MΩ] Rated allowable power No indication : /6 [W] Others : As specified Type No indication : Carbon resistor OMR : Oxide metal film resistor MFR : Metal film resistor MPR : Metal plate resistor UNFR : Uninflammable resistor FR : Fusible resistor Composition resistor /2 [W] is specified as /2S or Comp. (2)Capacitors Capacitance value or higher : [pf] less than : [µf] Withstand voltage No indication : DC5 Others : DC withstand voltage AC indicated : AC withstand voltage Electrolytic Capacitors 47/5[Example]: Capacitance value [µf]/withstand voltage (7)round symbol : LIVE side ground : ISOLATED(NEUTRAL) side ground : EARTH ground : DIITAL ground 5.NOTE FOR REPAIRIN SERVICE This model's power circuit is partly different in the ND. The difference of the ND is shown by the LIVE : ( ) side ND and the ISOLATED(NEUTRAL) : ( ) side ND. Therefore, care must be taken for the following points. ()Do not touch the LIVE side ND or the LIVE side ND and the ISOLATED(NEUTRAL) side ND 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 LIVE side ND and ISOLATED(NEUTRAL) side ND or never measure with a measuring apparatus measure with a measuring apparatus ( oscilloscope, etc.) the LIVE side ND and ISOLATED(NEUTRAL) side ND at the same time. If the above precaution is not respected, a fuse or any parts will be broken. Since the circuit diagram is a standard one, the circuit and circuit constants may be subject to change for improvement without any notice. NOTE Due improvement in performance, some part numbers show in the circuit diagram may not agree with those indicated in the part list. When ordering parts, please use the numbers that appear in the Parts List. (No.YA24)2-
