All Operational Difficulties
If this unit does not function properly for any reason, replace the battery with a new high-quality
battery (see "Battery Replacement" section). Low battery power can occasionally cause any number
of "apparent" operational difficulties. Replacing the battery with a new fresh battery will solve most
difficulties.
BATTERY REPLACEMENT
Erratic readings, a faint display, or no display are all indications that the battery must be replaced. To
replace the battery, remove the battery cap screw. Remove the battery cap by turning it in the
direction of the arrow (counter clockwise). Remove the exhausted battery and replace it with a new
1.5 volt size G-13 battery. Equivalent replacement batteries are: Ray-O-Vac RW42, Duracell D357,
Eveready 357. Make certain that the positive (+) side is facing you. Replace the battery cap.
Replace the battery cap screw and tighten securely.
