5-2. PRINTED WIRING BOARD AND
SCHEMATIC DIAGRAM INFORMATION
All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less
are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specifi ed.
All resistors are in ohms. k=1000, M=1000k
Indication of resistance, which does not have one for rating electrical
power, is as follows: Pitch : 5mm Rating electrical power :
1 1
/ W in resistance, / W and
4 10
: nonfl ammable resistor.
: fusible resistor.
: internal component.
: panel designation and adjustment for repair.
: earth ground
: earth-chassis
All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10M digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production tolerances.
All voltages are in V.
S : Measurement impossibillity.
: B+line.
: B-line. (Actual measured value may be different).
: signal path. (RF)
Circled numbers are waveform references.

The components identifi ed by shading and
for safety. Replace only with part number specifi ed.
The symbol indicates a fast operating fuse and is
displayed on the component side of the board. Replace only
with fuse of the same rating as marked.
Les composants identifi es per un trame et une marque
critiques pour la securite. Ne les remplacer que par une piece
portant le numero specifi e.
Le symbole indique une fusible a action rapide. Doit etre
remplace par une fusible de meme yaleur, comme maque.
