the hours and the minutes (Figure 4).
• You are now able to set the temperature unit (Fig-
ure 5). Press the MODE button to switch between
°C (Celsius) and °F (Fahrenheit). Set the required
temperature unit and confirm the entry by press-
ing the START button.
• The basic settings have now been configured. The
device switches off.
If no button is pressed for approximately 30 seconds
while configuring the basic settings, the device switches off automat-

Avoiding inaccurate measurements
Taking measured values directly from the middle ear (eardrum) en-
sures the most accurate temperature measurement. Measurements
taken on the surrounding tissue of the ear canal will result in lower
measured values and can lead to an incorrect diagnosis of a fever.
For this reason, it is very important to position the thermometer in the
ear correctly. It is essential to follow the instructions on positioning the
thermometer in the ear in the chapter "Measuring the temperature"
on page 12.
Rest for at least 5 minutes before taking the measurement.
Always measure the temperature in the same ear, as the temperature
values may vary from ear to ear.
In the following situations, you should take three consecutive tem-
perature measurements in the same ear and take the highest result as
the measured value:
– In children under three years of age with a vulnerable immune sys-
tem where the presence or absence of fever may be critical.
– If you are familiarising yourself with the device and are practis-
ing how to use the infrared ear thermometer correctly until you
achieve consistent measured values.
– If you feel the measured values are unusually low.
Make sure that the measuring sensor is always clean. A dirty or
clogged measuring sensor can lead to incorrect measurements.
