NOTE ON USING CIRCUIT DIAGRAMS

1.SAFETY
The components identified by the symbol and shading are critical for safety. For continued safety replace safety critical components only with manufactures recommende d parts.
2.SPECIFIED VOLTAGE AND WAVEFORM VALUES
The voltage and waveform values have been measured under the following con ditions.
(1)Input signal : Colour bar signal
(2)Setting positions of each knob/button and variable resistor
(3)Internal resistance of test er
:DC 20k
/V
(4)Oscillos cope sweeping time
:H
20µS/div
:V
5mS/div
:Others
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.
3.INDICATION OF PARTS SYMBOL [EXAMPLE]

5.NOT E FOR REPAIRING SERVI CE
This mode l's p ower circu it is pa rtly diffe rent in th e 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 ci rcuit and circuit constants may be subject to change for i mprovement 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, pl ease use t he numbers t hat appear in the Parts List.
