Two CR123A Lithium batteries are to be replaced every repack, every 500 jumps or when the unit displays Batt Low or Batt Rpl.
Unscrew Phillips head closing screw. Remove old batteries. Insert new batteries noting the polarity marks on the outside of the unit. Re-install battery back plate and tighten closing screw to snug.
