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.
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.
