NOTE ON USING CIRCUIT DIAGRAMS
1.SAFETY
The components identified by the
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.
5pin
(1)Input signal
(2)Setting positions of
each knob/button and
variable resistor
(3)Internal resistance of tester
(4)Oscilloscope sweeping time
(5)Voltage values
Since the voltage values of signal circuit vary to some extent
according to adjustments, use them as reference values.

4.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
:[K
]
the receptacle when, for example, the chassis is pulled out.
:[M
]
(2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL)
side GND or never measure with a measuring apparatus measure
with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND
:Carbon resistor
and ISOLATED(NEUTRAL) side GND at the same time.
:Oxide metal film resistor
If the above precaution is not respected , a fuse or any parts will be broken.
:Metal film resistor
Since the circuit diagram is a standard one, the circuit and
:Metal plate resistor
circuit constants may be subject to change for improvement
:Uninflammable resistor
without any notice.
:Fusible resistor
NOTE
Due improvement in performance, some part numbers show
in the circuit diagram may not agree with those indicated in
