SCHEMATIC DIAGRAMS 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:

 : 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 impossibility.
: 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 
!
 symbol are critical 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.
NOTE: The components identifi ed by a red outline and a   mark contain confi dential 
information. Specifi c instructions must be adhered to whenever these components 
are repaired and/or replaced.
