Measured temperature too
low, 3 short beeps are emitted.
Ambient temperature too high
(above 104.0˚F or 40.0˚C). 3
short beeps are emitted.
Ambient temperature too low
(below 50.0˚F or 10.0˚C). 3
short beeps are emitted.
Thermometer has
malfunctioned. 3 short beeps
are emitted.
Battery voltage is low.
Temperature measurement is
still allowed.
The thermometer should be
reset or the battery should be
replaced.
Probe may have been inserted
incorrectly. Retake temperature
measurement.
Take the measurement in
operating temperature range.
(50.0˚F -104.0˚F / 10.0˚C -
40.0˚C)
Take the measurement in operating
temperature range. (50.0˚F -
104.0˚F/ 10.0˚C - 40.0˚C)
Turn the thermometer off and
re-take temperature measurement.
Replace old battery with new
battery after taking the
measurement.
Replace the battery or reset the
thermometer by turning the
thermometer off and on again.
