THIS
NOTE
IS COMMON
FOR PRINTED WIRING
BOARDS AND SCHEMATIC
DIAGRAMS.
(In addition to this, the necessary note is printed in
each block.)
For printed wiring boards:
@
oO-~— =: indicated a lead wire mounted on the component
side.
e
: Through hole.
: Pattern from the side which enables seeing.
: Pattern of the rear side. *
Circled numbers refer to waveforms.
Caution:
Pattern face side:
Parts on
the pattern
face side seen
(Conductor Side)
from the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from
(Component Side)
the parts face are indicated.
For schematic diagrams:
@
Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minuts side of tantalum capa-
citor, because it is damaged by the heat.
All resistors are in ohms, 1/4W unless otherwise noted.
Chip resistor are 1/10W unless otherwise noted.
kQ: 10002, MQ:
1000k2.
All capacitors are in uF unless otherwise noted.
pF: uwuF
5OV or less are not indicated except for electrolytics and
tantalums.
All
variable
and
adjustable
resistors
have
characteristic
curve B, unless otherwise noted.
|
: nonflammable resistor.
: fusible resistor.
: panel designation.
: internal component.
: adjustment for repair. *
: Bt line, *
: B- line. *
: IN/OUT direction of B line (+, -). *
Circled numbers refer to waveforms. *
Voltage are dc between ground and measurement points. *
Readings are taken with a color-bar signal playback. *
Readings are taken with a digital multimeter (DC 10MQ). *
Voltage are taken with a VOM
(input impedance 10M). *
Voltage variations may
be noted
due to normal produc-
tion tolerances. *
e
*
: Indicates by the color red.
When
indicating
parts
by
refer-
ence
number,
please
include
the
board name.
Note:
The components
identi-
fied by mark
or dot-
ted
line with
mark
A / V
are critical for safety.
Replace
only with part
number specified.
