How to Replace the Fuses
The fuse in the Power Supply Unit, Processor Unit, monitor unit and sensor adapter
protects those units from overvoltage (overcurrent) and internal fault. If a unit cannot
be turned on, check if its fuse has blown. If the fuse has blown, find out the cause be-
fore replacing the fuse. If the fuse blows again after replacement, contact your dealer
for advice.
