5-4. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note:
•
All capacitors are in µF unless otherwise noted.
pF: µµF 50WV or less are not indicated except for electrolytics.
•
Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1 /4W
•
All resistors are in ohms.
• @:
nonflammable resistor.
•
Chip resister are 1 /1 OW unless otherwise noted.
•
~:
fusible resistor.
•
L:,,.:
internal component.
• D:
panel designation.
•
All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
. •
METAL FILM(: RN) resister in 0.5%, 1/4W unless otherwise
specified.
•
The components identified by
B
in this basic schematic
diagram have been carefully factory-selected for each set in
order to satisfy regulations regarding X-ray radiation.
Should replacement be required, replace only with the value
originally used.
•
When replacing components identified by
C.,
make the
necessary adjustments indicated. If results do not meet the
specified value, change the component identified by
B
and
repeat the adjustment until the specified value is achieved.
