If the fuse blows, the CV or CC indicators will not light and the power supply will not
operate. The fuse should not normally open unless a problem has developed in the
unit. Try to determine and correct the cause of the blown fuse, then replace only
with a fuse of the correct rating as listed below. The fuse is located on the rear panel
(see Figure 2
- Rear Panel ). Pull fuse compartment out with a flathead screwdriver
and replace fuse in holder.
