The following instructions are for use by qualified personnel only. To
avoid electrical shock, do not perform any servicing other than
contained in the operating instructions unless you are qualified to do
so.
FUSE REPLACEMENT
If the fuse blows, the CV, CC, or LED meter 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.
