Carefully insert the tip 1-2 cm into the anus. Minimum
measurement time: 30 seconds
Do not consume hot or cold food or drinks for at least 10
minutes before measuring body temperature. Insert the
tip into one of the two heat pockets under the tongue,
on the left- or right-hand side of the root of the tongue.
Close the mouth and breathe calmly through the nose.
Minimum measurement time: 60 seconds
The skin must be completely dry. Place the tip under the
arm, so that it is fully in contact with the skin. The ther-
mometer should be at right angles to the body. Place the
arm across the chest, so that the tip is tightly covered.
Minimum measurement time: 3 minutes.
and the thermometer switches to measuring mode. Place
the thermometer at the desired measurement point.
During measurement the current temperature is shown
on the display with a flashing “°C” symbol. If the increase
in temperature over a period of 16 seconds is less than
0.10 °C, the thermometer will beep. If the temperature
is being measured rectally, this beep means that the ap-
proximate final temperature is now being displayed; the
temperature will only change marginally from this point
on. If the temperature is being measured orally or under
the arm, it is important to stick to the intended minimum
measurement, irrespective of whether the device beeps.
At temperatures below 37.50°C, the normal signal tone
will sound (10 long, even tones). At temperatures of
37.50°C and higher, the fever alarm will sound (30 short
tones in sets of three). Read the temperature from the dis-
play. The thermometer will switch itself off automatically
after approx. 10 minutes. You can also turn it off earlier by
pressing the on/off button. The temperature will be saved
until the next one is measured.
Press the on/off button to switch on the thermometer.
A short signal tone confirms that the thermometer is
switched on. At the same time, all signals on the display
are illuminated as a visual functionality check. The last
measurement is then displayed for approx. 2 seconds
together with a small “M” symbol (M = memory). An in-
ternal test value of 37.00°C ± 0.01°C is then displayed
• Do not drop the thermometer. It is not resistant to shock
or impact.
• The thermometer contains small parts (battery etc.)
which children could swallow. Do not let children use
the device unsupervised.
• Protect the device from high temperatures and direct
sunlight.
• Do not open the casing (except to change the battery).
• Do not walk, run or speak while using the thermometer.
• Keep the thermometer in the plastic case.
• Using the thermometer other than as intended can lead
to inaccurate measurements.
• The use of this device in the vicinity of mobile phones,
microwaves or other devices with strong electromag-
netic fields can cause malfunctions. Maintain a distance
of at least three metres from such devices when using
the thermometer.
CLASSIFICATION OF THE TEMPERATURES MEASURED
Temperatures measured rectally are generally 0.5 °C
higher than those measured orally, while temperatures
measured under the arm are 0.5 °C lower.
Warning: Always consult a doctor if the reading shows
a high fever.
37.5 °C to 37.9 °C: elevated temperature
38.0 °C to 38.9 °C: moderate fever
39.0 °C and above: high fever
CHANGING THE BATTERY
If the symbol appears after all signals have been illu-
minated in the functionality check, a battery replacement
is required.
• Do not use a metal object to push the battery out of
its holder.
• Carefully pull the battery holder about 1 cm out of the
casing.
• Remove the battery compartment cover from the ther-
mometer.
• Insert a new battery (LR41 or SR41, 1.55V) with the +
sign towards the top.
• Push the battery holder back into the casing and replace
the battery compartment cover. Take care not to damage
or misalign the seal when doing this.
