1-2.  PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS INFORMATION
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.
Les composants identifi es per un trame et une marque 
!
 sont critiques pour la 
securite.  Ne les remplacer que par une piece portant le numero specifi e.
Le symbole 
 indique une fusible a action rapide. Doit etre remplace par une 
fusible de meme yaleur, comme maque.
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. 
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: 
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
 digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production 
tolerances.
