2. Information about this thermometer
The temperature measurement varies depending on the part of the body where the measurement is taken. In a healthy person, the variance can be between 0.2 °C and 1 °C (0.4 °F and 1.8 °F) in different parts of the body.

Beurer tip
• Temperatures measured with different thermometers should never be compared
with one another.
• Tell your doctor what type of thermometer you used to take your temperature
and on what part of the body. Also bear this in mind if you are diagnosing yourself.

Holding the thermometer for too long in the hand before taking a measurement can
cause the device to warm up. This means the measurement could be incorrect.

Influences on body temperature

• A person’s individual metabolism
• Age
Body temperature is higher in babies and toddlers than in adults. Greater temperature fluctuations occur faster and more often in children. Normal body temperature decreases with age.
• Clothing
• Outside temperature
Time of day
Body temperature is lower in the morning and increases throughout the day towards evening.
Activities
Physical and, to a lesser extent, mental activities increase body temperature.

Beurer tip
Taking the body temperature provides a current measurement of a person’s temperature. If you are uncertain about interpreting the results or if the values are
abnormal (e.g. fever), please consult your doctor. This also applies in the case of
slight temperature changes if there are other symptoms of illness such as agitation,
severe sweating, flushed skin, fast pulse rate, tendency to collapse, etc.

Briefly press the On/Off button POWER.
After a brief self-test and two short beeps the device is ready for forehead temperature measurement. The device is in forehead temperature mode. This is indicated by the symbol.

Beurer tip
Remember that
• physical activity, increased perspiration on the forehead, taking vasoconstrictive
medication and skin irritations can distort the result,
• the forehead, or the temples, must be free from perspiration and cosmetics.

During measurement you will hear short beeps (only if the acoustic signal is activated), which signal that the thermometer has found a new highest measurement.
End of measurement is signalled by a long beep.
Release the SCAN button.
You can now read the measured value.
In addition to the temperature, the fever or no fever symbols also appear in the display:
The no fever symbol indicates that the body temperature is within normal range; the
fever symbol indicates a measurement equal to or higher than 38°C (100.4°F), which
triggers a temperature alarm.
If the acoustic signal is switched on, three beeps will sound once the measurement is complete if the temperature is equal to or higher than 38°C (100.4 °F).
The measuring time is usually 2 seconds but may take up to 30 seconds.
When two short beeps sound and the forehead symbol stops flashing, the device is
ready to take another measurement.
The measurement is automatically saved with the date/time and the “fever” / “no fever” classification.
