• CN901 of XVM-F65WL is connected to Connection Box
with a monitor cable.
Power voltage is dc 14.4 V from BATT cord of the Connec-
tion Box and fed with regulated dc power supply.
Voltage and waveforms are measured at input the color
bar signal from the Connection Box.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
