specified.
• C : panel designation.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• CN1 of XVM-753W is connected to CN3 (MONITOR OUT)
of Hideaway Unit (XT-993V) with a monitor cable.
Power voltage is dc 14.4 V from ACC cord of the
Hideaway Unit and fed with regulated dc power
supply. (XVM-753W)
• CN1 of XVM-753W is connected to CN3 (MONITOR OUT)
of Hideaway Unit (XT-993V) with a monitor cable.
Voltage and waveforms are measured at input the color
bar signal from INPUT 1 VIDEO (J5-3) jack of the
Hideaway Unit. (XVM-753W)
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
