WARNING!
DO NOT attempt this maintenance action with power applied to the
instrument either through its test leads or by way of the “Press to
Test” button being pressed.
To replace the fuse, turn the instrument upside down on a clean, flat
surface to expose battery compartment.
1. Remove the battery cover retaining screw.
2. Apply outward pressure (away from the carrying handle) on the
battery cover and remove it from the instrument.
3. Remove and replace the fuse with specified replacement
size and type.
4. Replace battery compartment cover.
