See Figures 6Ć2 and 6Ć37 for the location of the line fuse and the A14 I/O
board fuses, respectively.
When a fuse must be replaced, unsolder the fuse from the board. Be careful
not to damage the solder pads on the board. (It may be helpful to straighten
the fuse leads on the rear of the board before removing the leads from their
holes in the circuit board.) Refer to the Parts List section for the correct value
and part number of each fuse.
