WQ-T2812
NOTES ON SCHEMATIC DIAGRAM
e Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor.
e Capacitor:
To
indicate
the
unit
of
capacitor,
a
symbol
P
is
used:
this
symbol P means micro-micro-farad and the unit of the
Capacitor without such a symbol is microfarad. As to elec-
trolytic capacitor, the expression ‘‘capacitance/withstand
voltage”’ is used.
(CH), (RH), (TH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
e The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chassis
with no signal given.
( ): AM mode
Marking except for (
