1-2. PRINTED WIRING 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 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:

: 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.

Circled numbers are waveform references.
The components identifi ed by shading and
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.
See Appendix A: Encryption Key Components in the back of this manual.
