9.2 Replacing the fuse

The DIFF contains a fuse (5x20 mm 250V / 5A slow). The fuse is placed on the right side of the display
unit. The fuse holder can be opened by turning the holder carefully with a big screwdriver. Take care that
the batteries are in the right position before putting the fuse back in.
The fuse in the DIFF should only be replaced with the original type: 5x20 mm 250V / 5A slow.
Repair can be needed if a fuse replacement does not solve the problem.
