NOTE UPON USING ROUTINE DIAGRAMS

1 ) SAFETY

The constituents identified by the symbol and shading are critical for security. For continued safety exchange safety ciritical components simply with produces recommended parts. Type No indication LOGISTIK PP MPP MF TF BP TAN (3)Coils Simply no unit Others: Original environment position when shipped: POWER 20kΩ/V: They would: V: Othters (5)Voltage principles 20µs as well as div 5ms / div Sweeping time is particular (4)Power Supply: B1: 9V Respective voltage values will be indicated (5)Test point: Test out point (6)Connecting method: Connector: Wrapping or soldering: Only test stage display: B2 (12V): 5V: [µH]#@@#@!!: As specified: Ceramic capacitor: Metalized mylar capacitor: Polypropylene capacitor: Metalized thermoplastic-polymer capacitor: Metalized film capacitor: Thin film capacitor: Bipolar electrolytic capacitor: Tantalum capacitor

2 . PARTICULAR VOLTAGE AND WAVEFORM PRINCIPLES

The volts and waveform values had been measured underneath the following circumstances. (1)Input sign (2)Setting positions of each knob/button and variable resistor (3)Internal resistance of tester (4)Oscilloscope sweeping time: Colour bar signal

: Almost all DC voltage values

Considering that the voltage principles of transmission circuit change to some extent relating to modifications, use them since reference ideals.

5. TAKE NOTE FOR REPAIRING SERVICE

This model's electrical power circuit is definitely partly diverse in the GND. The difference of the GND is shown by the LIVE: ( ) aspect GND as well as the ISOLATED(NEUTRAL): ( ) aspect GND. Consequently , care should be taken intended for the following items. (1)Do certainly not touch the LIVE area GND and also the LIVE side GND and the ISOLATED(NEUTRAL) side GND together. if the previously mentioned caution is usually not respected, an electric distress may be induced. Therefore , make certain that the power cable is surely removed from the receptacle when, for instance , the chassis is pulled out. (2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL) area GND or never evaluate with a measuring apparatus measure with a computing apparatus ( oscilloscope, and so forth ) the LIVE aspect GND and ISOLATED(NEUTRAL) area GND simultaneously. If the over precaution is not respectable, a merge or any parts will be busted. Since the circuit diagram is actually a standard 1, the outlet and signal constants can be subject to modify for improvement without any detect. NOTE Because of improvement in performance, a few part numbers show in the signal diagram might not agree with all those indicated in the part list. When buying parts, you should use the amounts that can be found in the Parts List.

Composition resistor 1/2 [W] is particular as 1/2S or Comp.

AC mentioned: AC endure voltage [V] Electrolytic Capacitors 47/50[Example]: Capacitance worth [ВµF]/withstand voltage[V]
