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.

Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
The components identifi ed by X in this basic schematic diagram
have been carefully factory-selected for each set in order to satisfy
regulations regarding X-ray radiation. Should replacement be
necessary, replace only with the value originally used.
