After a battery replacement or any other repair, verify

Replacing the air intake filter
The air intake filter serves to remove solid particles from
air before it is drawn through the LI-600 porometry sys-
tem. A 0.45 micron filter (part number 301-19838) is a
direct replacement for the original 1.0 micron filter
(part number 301-16918).
Follow these steps to replace the air intake filter.
