ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly
for any reason, replace the battery with a
new high quality battery (see the “Battery
Replacement” section). Low battery power
can occasionally cause any number of “ap-
parent” operational difculties. Replacing the
battery with a new fresh battery will solve
most difculties.
MIN/MAX MEMORY
1. Press MAX/MIN to display maximum
recorded reading.
2. Press MAX/MIN again to display the
minimum record reading.
3. Press MAX/MIN once more to return the
display to current reading.
4. Switch thermometer off then on to reset
the memory reading to current reading.
5. Reset the memory once before taking
new maximum or minimum reading.
BATTERY REPLACEMENT
Erratic readings, a faint display, or no display
are all indicators that the battery must be
replaced. To replace the battery, loosen the
two screws at the rear of the case. Remove
the face of the thermometer taking care not
to disconnect the internal wiring. Replace
exhausted battery with a new 1.5-volt, silver
oxide, 389 size battery. Make certain positive
(+) side is visible. Replace the face of the unit
and tighten the screws. Do not over-tighten
the screws as this may damage the unit.
NOTE: When replacing the face of the unit, care-
fully ensure the back is properly in place and the
screws are tightened securely to maintain the unit’s
water-resistance.
