q NOTE ON USING CIRCUIT DIAGRAMS
The components identified by the symbol and shading are critical for safety. For continued safety replace safety critical components only with manufactures recommended parts.
2. SPECIFIED VOLTAGE AND WAVEFORM VALUES
The voltage and waveform values have been measured under the following conditions. (1) Input signal : Color bar signal (2) Setting positions of each knob/button and variable resistor : Original setting position when shipped (3) Internal resistance of tester : DC 20kØ/V (4) Oscilloscope sweeping time : H 20µS/div :V 5mS/div : Others Sweeping time is specified (5) Voltage values : All DC voltage values
9 Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values.
9Respective voltage values are indicated
(5) Test point : Test point : Only test point display (6) Connecting method : Connector : Wrapping or soldering : Receptacle (7) Ground symbol : LIVE side ground : ISOLATED(NEUTRAL) side ground : EARTH ground : DIGITAL ground
