FUSE REPLACEMENT
If the need to check or replace a fuse arises please follow Steps 1 through 4 carefully.
1. Turn scale power switch to the OFF position and unplug power cord from wall outlet.
ALWAYS remove power source from scale before removing or
replacing fuse to prevent risk of electrical shock.
2. Press inward on the fuse holder cap, turn counterclockwise and release. The cap along with the
fuse should then be ejected on the fuse holder. See figure 4.
3. Pull out the old fuse. Place new fuse in holder: 3AG 1/4 ASB type for 110 VAC; 3AG 1/8 ASB
type for 220 VAC. Snap the fuse holder back into position.
4. The power may now be turned on.
To prevent risk of fire, be certain to use type and rating recommended for your Model
