All voltages are in V.
S : Measurement impossibility.
: B+line.
: B-line. (Actual measured value may be different).

Circled numbers are waveform references.
The components identi
fi
ed by shading and
!
symbol are critical for safety. Replace
only with part number speci
fi
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.

sont critiques pour la
securite. Ne les remplacer que par une piece portant le numero speci

e.
Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
NOTE: The components identi
fi
ed by a red outline and a mark contain con
fi
dential
information. Speci
fi
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.
All capacitors are in

F 50WV or
less are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise speci

ed.
All resistors are in ohms. k

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.
