5.NOTE FOR REPAIRING SERVICE
:1/ 16 [W]
This model's power circuit is partly different in the GND. The
difference of the GND is shown by the LIVE : (
:As specified
ISOLATED(NEUTRAL) : (
taken for the following points.
:Carbon resistor
(1)Do not touch the LIVE side GND or the LIVE side GND and the
:Oxide metal film resistor
ISOLATED(NEUTRAL) side GND simultaneously. If the above
:Metal film resistor
caution is not respected, an electric shock may be caused.
Therefore, make sure that the power cord is surely removed from
:Metal plate resistor
the receptacle when, for example, the chassis is pulled out.
:Uninflammable resistor
(2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL)
:Fusible resistor
side GND or never measure with a measuring apparatus measure
with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND
and ISOLATED(NEUTRAL) side GND at the same time.
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

NOTE
:DC withstand voltage [V]
Due improvement in performance, some part numbers show
in the circuit diagram may not agree with those indicated in

When ordering parts, please use the numbers that appear
in the Parts List.
