Ensure that the positioning of the probe is
correct and remains stable.
Allow the thermometer to remain for 30
minutes in a room where the temperature is
between 50 and 104 °F / 10 and 40 °C.
Make sure the probe tip and lens are clean and
a new, clean probe cover is attached. Make
sure the thermometer is properly inserted into
the ear canal.
Then, take a new temperature.
Wait 1 minute until the thermo-meter turns
off automatically, then turn on again.
... reset the thermometer by re-moving the
batteries and putting them back in.
