symbol are critical for safety. Replace
only with part number specified.
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.

fusible de meme yaleur, comme maque.
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.
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

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
