1. SAFETY
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
: Colour bar signal
(2) Setting positions of each knob/button and
variable resistor
: Original setting position when
shipped
(3)Internal resistance of tester : DC 20k
/V
(4)Oscilloscope 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.

5. NOTE FOR REPAIRING SERVICE
This model's power circuit is partly different in the 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 the LIVE side GND and
ISOLATED (NEUTRAL) side GND at the same time with a measuring
apparatus (oscilloscope, etc.). If the above precaution is not
respected, a fuse or any parts will be broken.
Since the circuit diagram is a standard one, the circuit
and circuit constants may be subject to change for
improvement 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, please use the numbers that
appear in the Parts List.
