4-2.  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
Ω=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating electrical 
power, is as follows: 
Pitch : 5mm

 : 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
Ω 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).

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.

Le symbole

Circled numbers are waveform references.
The components identifi ed by X 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 
necessary, replace only with the value originally used.
When replacing components identifi ed by Y, make the necessary 
adjustments as indicated.  If the results do not meet the specifi ed 
value, change the component identifi ed by X and repeat the 
adjustment until the specifi ed value is achieved. 
(Refer to Safety Related Adjusments Section 2)
When replacing the parts listed in the table below, it is important to 
perform the related adjustments.
