: Test Point position
/ S GND: Chassis Earth (Cold)
P GND: Line Earth (Hot)
4. Voltage Measurement
Voltage is measured by a DC voltmeter.
Conditions of the measurement are the following:
Power Source ....................... AC110-127V, 50/60Hz /
220-240V, 50/60Hz
Receiving Signal ................... Colour Bar signal (RF)
All customer’s control ........... Maximum positions
5. This schematic diagram is the latest at the time of printing
and subject to change without notice.
Remarks:
1. The Power Circuit contains a circuit area which uses a
separate power supply or you may be shocked.
The circuit defined by HOT and COLD indications in the
schematic diagram. Take the following precautions.
All circuits, except the Power Circuit, are cold.
Precautions:
a. Do not touch the hot part or the hot and cold parts at
the same time or you may be shocked.
b. Do not short-circuit the hot and cold circuits or a fuse
may blow and parts may break.
c. Do not connect an instrument, such as an oscilloscope,
to the hot and cold circuits simultaneously or a fuse
may blow.
d. Make sure to disconnect the power plug before
removing the chassis.
