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.

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 (Refer to Safety Related Adjustments
