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. Type No indication MM PP MPP MF TF BP TAN (3)Coils No unit Others : Original setting position when shipped : DC 20k? /V :H :V : Othters (5)Voltage values 20 µs / div 5ms / div Sweeping time is specified (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 : [ µH] : As specified : Ceramic capacitor : Metalized mylar capacitor : Polypropylene capacitor : Metalized polypropylene capacitor : Metalized film capacitor : Thin film capacitor : Bipolar electrolytic capacitor : Tantalum capacitor . 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 som e extent according to adjustments, use them as reference values. 3. INDICATION OF PARTS SYMBOL [EXAMPLE] In the PW board : R209 R209 (7)Ground symbol : LIVE side ground : ISOLATED(NEUTRAL) side ground : [? : [k? ] : [M? ] : EARTH ground : DIGITAL ground : Receptacle 4.

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 LIVE side GND and ISOLATED(NEUTRAL) side GND or never measure with a measuring apparatus measure with a measuring apparatus ( oscilloscope, etc. ) the LIVE side GND and ISOLATED(NEUTRAL) side GND 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 an y 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. Composition resistor 1/2 [W] is specified as 1/2S or Comp.
