Measuring temperature
Tips for proper measurement
External factors can influence your body tempera
ture. In the following cases, wait at least 30 minu
tes before taking your temperature:
- When you have been lying on your ear
- When you had your ears covered
- When you have been exposed to very low or
very high temperatures
- When you have been swimming or bathing
- If you wear earplugs or hearing aids, remove
them first
We do not advise you to use the device in the follo
wing circumstances as this may cause inaccurate
measurements:
- When the temperature of the storage area dif
fers from the temperature of the measuring
area. In this case, wait at least 30 minutes befo
re you use the device.
- If you are using ear drops or other ear medicati
on. In this case, measure the temperature in the
untreated ear (if any).

Body temperature

Normal body temperature is a range. A person's
normal temperature range tends to decrease with
age. The following table shows normal temperatu
re ranges by age.
The range of normal body temperature varies from
person to person and can be influenced by many
factors such as time of day, level of activity and
emotions.
Age
0-2 years
3-10 years
11-65 years
> 65 years
