BATTERY REPLACEMENT
Erratic readings, a faint display, no display or
appearing on the display are all indications that the
battery must be replaced. Using a coin, turn the
battery cover on back of the unit in the direction of
the “open” arrow. Remove the exhausted battery
and replace with a new 1.5 volt silver-oxide 389
size battery. Make certain positive (+) side is vis-
ible. Replace battery cover.
