PRINTED CIRCUIT BOARDS AND 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 specified.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating
electrical power, is as follows:
/ W in resistance, / W and
1 1
4 10
: nonflammable 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 10MΩ 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 identified by shading and
only with part number specified.
The symbol indicates a fast-blow fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.
NOTE: The components identified by a red outline and a mark contain confidential
information. Specific instructions must be adhered to whenever these components
are repaired and/or replaced.
See Appendix A: Encryption Key Components in the back of this manual.
