7.3 How to Replace the Fuse
If the power cannot be turned on, the fuse may have blown. To take out the fuse from
the fuse holder on the power cable, hold both ends of the fuse holder and pull the fuse
holder apart without bending the fuse holder. When you replace the fuse, confirm that
the fuse is tightly fixed on the metal contact located inside the fuse holder. If the metal
contact holding the fuse is loose, the fuse holder may become hot.
