5 Schematic Diagram
Notes :
1. Resistor
All resistors are carbon 1/4 W resistors unless marked as follows :
Unit of resistance is OHM (
Ω
) (K = 1 000 M = 1 000 000)
2. Capacitor
All capacitors are ceramic 50 V capacitors unless marked as follows :
Unit of capacitance is µF unless otherwise noted.
3. Coil
Unit of inductance is µH, unless otherwise noted.
4. Test Point
: Test Point position
5. Earth Symbol
: Chassis Earth (Cold)
: Line Earth (Hot)
6. Voltage Measurement
Voltage is measured using DC voltmeter.
Conditions of the measurement are the following :
Power Source....................AC SINGLE 220-240 V, 50/60 Hz
Receiving Signal................Colour Bar signal (RF)
All customer’s controls.......Maximum positions
7. Number in red circle indicates waveform number.
(See waveform pattern table)
