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.
