users. Therefore, it is essential that the probe is clean
before each measurement. For cleaning, follow the
instructions in the «Cleaning and Disinfecting» section.
• After cleaning the measuring sensor 1 with alcohol,
wait 5 minutes before taking the next measurement,
in order to allow the thermometer to reach its operating
reference temperature.
• For an infant, it is best to have the child lying flat with his/
her head sideways so the ear is facing upwards. For an
older child or adult, it is best to stand behind and slightly
to the side of the patient.
• Always take the temperature in the same ear, since the
temperature readings may be different from ear to ear.
• In the following situations it is recommended that three
temperatures in the same ear be taken and the highest
one taken as the reading:
1. New born infants in the first 100 days.
2. Children under three years of age with a compromised
immune system and for whom the presence or absence
of fever is critical.
3. When the user is learning how to use the thermometer
for the first time until he/she has familiarized himself/
herself with the device and obtains consistent readings.
4. If the measurement is surprisingly low.
