Fuse Replacement
Electric shock hazard:
The fuse is an integral part of the overvoltage protection. When
fuse replacement is necessary, refer to "Specifications" for the
correct type, size and capacity. Using any other type of fuse will
void the overvoltage protection rating of the unit.
Failure to observe this warning could result in severe injury or
death.
1. Disconnect the unit from the circuit. Turn the unit OFF.
2. Remove the screw from the battery compartment cover. Remove
the battery compartment cover.
3. Remove the screws from the back cover. Remove the back cover,
taking care not to stress the battery connector leads.
4. Replace the fuse.
5. Replace the covers and screws.
Cleaning
Periodically wipe the case with a damp cloth and mild detergent; do
not use abrasives or solvents.
