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.

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.
