Appendix H: Battery Replacement
When the battery status indicator is empty the batteries should be changed
immediately. For optimum performance replace the batteries with 3 AA size
alkaline batteries. The procedure for replacing batteries is as follows:
1. Turn the analyzer over and locate the phillips head battery cover screw. See
picture below.
2. Loosen the screw. Pull out on the screw to remove the battery cover.
3. Remove the old batteries and observing the polartiy markings in the battery
compartment, install the new batteries.
4. Re-install the battery cover by fitting the bottom part in first.
5. Tighten the battery cover screw.
