MAINTENANCE
WARNING
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 LED indicator 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. For
110 or 120V operation a 1.6A, 250 V, 3AG fuse should
be used and for 220 or 240V operation a 0.75A, 250V,
3AG fuse should be used. The fuse is located on the rear
panel (see Fig. 2).
