. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAM:
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 :
« O— : indicates a lead wire mounted on the componet side.
° @ =: Through hole..
* [BMJ : Pattern from the side which enables seeing.
¢ [HERR : Pattern of the rear side.
* Circled numbers refer to waveforms.
Note :
Conductor side: Parts on the conductor side being seen from
the conductor are stated.
Component side: Parts on the component side being seen
from the component are stated.
For schematic diagram :
* Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minuts side of tantalum capacitor,
because it is damaged by the heat.
¢ All resistors are in ohms, %W (chip resistors : 1710W) unless
otherwise noted. k2 : 10002, MQ: 1000k Q.
e All capacitors are in uF unless otherwise noted. pF: mu F.
50V or less are not indicated except for electrolytics and
tantalums.
e All variable and adjustable resistors have characteristic carve B,
unless otherwise noted.
° at : nonflammeble resistor.
° WU} : fusible resistor.
* [_] : panel designation.
° A _— : internal component.
. tC] : adjustment for repair.
¢ sme © B+ line.
¢ mma: B— line.
* Zp :IN/OUT direction of B line (+, —).
¢ Circled numbers refer to waveforms.
*« Voltages are dc between ground and measurement points.
e Readings are taken with color-bar signal input.
e Readings are taken with a digital multimeter (DC1OM Q),
¢ Voltages are taken with a VOM (Input impedance 10M Q).
¢ Voltage variations may be noted due to normal production
tolerances.
line with mark are critical for safety.
Note: The ith marks ae erie by mark A or dotted
Replace only with part number specified.
When indicating parts by refer-
ence number, please include the
board name.
