4.INDICATIONS ON THE CIRCUIT DIAGRAM
(1)Resistors:LIVE side ground
Resistance value:ISOLATED(NEUTRAL) side ground
No unit:[]:EARTH ground
K:[K ]:DIGITAL ground
M:[M ]
Rated allowable power5.NOTE FOR REPAIRING SERVICE
No indication:1/ 16 [W]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
Others:As specified
ISOLATED(NEUTRAL) : ( ) side GND.Therefore, care must be
Type
taken for the following points.
No indication:Carbon resistor
(1)Do not touch the LIVE side GND or the LIVE side GND and the
OMR:Oxide metal film resistor
ISOLATED(NEUTRAL) side GND simultaneously. If the above
MFR:Metal film resistor caution is not respected, an electric shock may be caused.
MPR:Metal plate resistor Therefore, make sure that the power cord is surely removed from
the receptacle when, for example, the chassis is pulled out.
UNFR:Uninflammable resistor
FR:Fusible resistor(2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL)
side GND or never measure with a measuring apparatus measure
Composition resistor 1/2 [W] is specified as 1/2S or Comp.
with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND
(2)Capacitors and ISOLATED(NEUTRAL) side GND at the same time.
Capacitance value If the above precaution is not respected , a fuse or any parts will be broken.
1 or higher:[pF]Since the circuit diagram is a standard one, the circuit and
less than 1:[?F]circ uit constants may be subject to change for improvement
without any notice.
Withstand voltage
No indication :DC50[V]NOTE
Others:DC withstand voltage [V]Due improvement in performance, some part numbers show
in th e circuit diagram may not agree with those indicated in
AC indicated :AC withstand voltage [V]
the part list.
Electrolytic Capacitors
When ordering parts, please use the numbers that appear
47/50[Example]:Capacitance value [?F]/withstand voltage[V]
in the Parts List.
