FUSE REPLACEMENT
1. Use a small screwdriver as shown to slide the fuse cover
out from the power inlet module. The fuse can be found
inside the fuse cover module after it is pulled out.
NOTE: A SMALL COMPARTMENT IS ALSO PROVIDED WITHIN THE FUSE COVER
MODULE FOR STORING A SPARE FUSE.
2. After replacing the fuse with another of identical
specifications, push the fuse cover module fully back into
place, ensuring that the fuse has snapped onto the fuse
holder inside the power inlet module.
