Scientific studies have shown that the ear is
ideally suited to measure the body temperature.
The body temperature is controlled by the
hypothalamus, the blood vessels of which also
supply the eardrum with blood. It is therefore
advantageous to measure the body temperature
whenever possible in the ear as shown in Fig. 1.

2.1 Intended use
The Ear and F hermometer is an infrared
temperature measurement device with which you
can easily and straightforwardly carry out precise
measurements of the body temperature on the
forehead or in the ear as well as the temperature
of liquids or surfaces. An acoustic signal indicates
the end of the temperature measurement; then,
you can read the temperature measured on the
LCD display. The device can save and display the
data of the last 9 body temperature measure-
ments on the forehead or in the ear. Green / red
indicator lights signalise if the body temperature
measured is in the normal range (green) or if the
body temperature is too high (red). The torch
function facilitates orientation and application in
the dark.

3.6.0 Whenever possible, always measure the
body temperature in the same ear, since the
temperature might be different in the right
and left ear.
Repeat the measurements approx. every 15
minutes if the measurement results are un-
usually low or do not reflect your personal
feeling. In this case, also carry out a com-
parative oral or rectal measurement using a
conventional clinical thermometer if
possible. If in doubt, consult your doctor!
Do not start a measurement immediately if
the device was stored in a place with a great
temperature difference as compared to the
place in which the measurement is to be
performed. Both the device and the people
whose body temperature is measured should
have been in the same environment for at
least 30 minutes.
Earwax or oily skin on the forehead might
result in inaccurate measurements. There-
fore, clean the ear and / or the forehead be-
fore carrying out a measurement. After-
wards, wait for approx. 5 - 10 minutes
before measuring the temperature.
Do not perform any measurements in the
ear if you suffer from an ear disease or if
there is still water in the ear (e.g. after
having taken a shower, after swimming...).
Do not use the device if it is damaged. Using
a damaged device might result in injuries,
serious risks and inaccurate measurement
results.

If the temperature of people using hearing
aids or earplugs is to be measured in the
ear, it is recommended to wait for approx.
30 minutes after such equipment has been
removed from the ear and only then carry
out a measurement of the temperature.
If the device has been held in your hand for
a long period of time, the measurement
result might be distorted by the heating of
the device resulting from this.
Please note that certain conditions might
have an impact on the measurement of the
body temperature in the ear, for example, if
the ear was covered, after swimming or
after having taken a bath, if the ear was ex-
posed to particularly high or low tempera-
tures or if you had lain on one ear for a
longer period of time.
Certain circumstances such as your age,
clothing, the outside temperature, physical
activities, your individual metabolism and
the time of the day can, as a matter of
principle, have an impact on the body
temperature.
Babies and toddlers have a higher body
temperature than adults. With increasing
age, the body temperature decreases. In
most cases, temperature fluctuations are
higher for children and occur more quickly
and more frequently.
If ear drops or other medication were
administered in one ear, the measurement of
the body temperature should be carried out
in the other ear.

The range of the normal body temperature differs
from one person to another and is determined by
many factors: age, sex, time of day, location and
type of the temperature measurement, level of
activity, emotional state, influence by medication
and other factors.
For instance, the body temperature of children is
approx. 0.9 0.5 °C higher than the body tem-
perature of adults. While asleep, most people have
a lower body temperature and the body tempera-
ture increases during the course of the day.

The normal value of the body temperature is not a
fixed value, but rather a temperature range. In
general, the body temperature decreases with
increasing age. The following table shows the
respective normal temperature ranges for different
age groups:
The body temperature is the internal temperature
of the body (core temperature). It fluctuates
during the course of the day and is lowest in the
early morning and highest in the late afternoon.

When measuring the body temperature, it is
important to determine, if possible, the body core
temperature corresponding to the temperature of
the inner organs. Research findings have shown
that the ear is ideally suited to measure the body
temperature, since the hypothalamus (the area of
the brain controlling the body temperature) and
the eardrum are supplied with blood via joint
blood vessels. Changes in the body temperature
can thus be determined more quickly and more
precisely than on other parts of the body. There-
fore, it is advantageous to measure the body
temperature, whenever possible, in the ear as
shown in Fig. 3 on page 15.
4.2 Advantages of measuring the
body temperature in the ear
In order to determine your own body temperature
and the body temperature of your family
members, it is recommended to perform measure-
ments of the body temperature when in a healthy
condition on three to four consecutive days at dif-
ferent times of the day. Thus, you can determine
the normal body temperature and write it down in
order to be able to compare the temperature
measurements to the normal values you have
determined when required.
Measurements performed on different parts of the
human body produce different results: Usually, the
body temperature measured rectally is approx.
0.5 0.3 °C higher than the body temperature
measured in the mouth, and this, in turn, is
higher than the body temperature
measured in the armpit.

For children older than 12 months and
adults:
Gently pull the ear backwards and carefully insert
the measuring probe along the ear canal in order
to ensure that the measuring probe is directed
towards the eardrum (see Fig. 3).
For babies younger than 12 months:
Gently pull the ear slightly diagonally backwards
in order to straighten the ear canal. Carefully
insert the measuring probe into the ear canal in
order to ensure that the measuring probe is
directed towards the eardrum (see Fig. 3).

ATTENTION - IMPORTANT INFORMATION
concerning the “Cleaning” warning indicator:
If, after several temperature measurements, the
device's green backlighting starts to flash for
approx. 1 minute with acoustic signal output, this
is not a malfunction, but the “Cleaning”
warning indicator! In this respect, please read
section 17.0 on page 37! If this warning indicator
is not switched off by pressing the MEM button,
this indicator will occur every time you try to per-
form a measurement and will disable subsequent
temperature measurements!
PLEASE NOTE: If “Lo” or “Hi” are shown on the
display after a measurement has been performed,
the permissible measuring range was fallen short
of or exceeded during the measurement.
PLEASE NOTE: If you wish to immediately return
to the standby mode from the setting or the
memory mode, you must simultaneously press
the ( ) “Ear measurement” and ( ) “Forehead
measurement” buttons. The device, however, also
