The Braun ThermoScan thermometer has been carefully developed
for accurate, safe and fast temperature measurements in the ear.
The shape of the thermometer prevents it from being inserted too far
into the ear canal to hurt the eardrum.
However, as with any thermometer, proper technique is critical to
obtaining accurate temperatures. Therefore, read the use
instructions carefully and thoroughly.
Important
• The operating ambient temperature range for this thermometer
is 10–40 °C (50–104 °F).
• Do not expose the thermometer to temperature extremes
(below –20 °C / –4 °F or over 50 °C / 122 °F) nor excessive humidity
(> 95 % RH).
• This thermometer must only be used with genuine Braun
ThermoScan Lens Filters (LF 40). Never use this thermometer
without a new, clean lens filter attached.
• Keep lens filters out of reach of children.
• This thermometer is intended for household use only.
• Use of this thermometer is not intended as a substitute for con-
sultation with your physician.
How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat generated by the
eardrum and surrounding tissues. To avoid gross temperature dif-
ferences, the sensor itself is brought to a temperature close to that of
the human body. When the Braun ThermoScan is placed in the ear,
it continuously monitors the infrared radiation. The measurement will
be finished and the result is displayed, when an accurate reading can
be assured.
Why measure in the ear?
The goal of thermometry is to measure core body temperature which
is the temperature of the vital organs. Ear temperatures accurately
reflect core body temperature, since the eardrum shares blood supply
with the temperature control center in the brain, the hypothalamus.
Therefore, changes in body temperature are reflected sooner and more
accurately in the ear than at other sites.
• Axillary temperatures only measure skin temperature and therefore,
are not a reliable indicator of core body temperature.
• Oral temperatures are influenced by drinking, eating and breathing.
• Rectal temperatures lag behind changes in core body temperature
and there is a risk of cross-contamination.

Body temperature
Normal body temperature is a range. The following table shows
that this normal range also varies by site. Therefore, readings from
different sites should not be directly compared.
• As well, a person’s normal temperature range tends to decrease
with age. The following table shows normal ThermoScan ranges
by age.
However, the range of normal also varies from person to person
and fluctuates throughout the day. It is therefore important to deter-
mine your normal temperature range. This is easily done using Braun
ThermoScan. Practice taking temperatures on yourself and healthy
family members to determine their normal temperature ranges.
Note: When consulting your physician, communicate that the
ThermoScan temperature is a temperature measured in the ear and
if possible, note the individual’s normal ThermoScan temperature
range as additional reference.
Normal ranges by site:
Axillary: 34.7 – 37.3 °C 94.5 – 99.1 °F
Oral: 35.5 – 37.5 °C 95.9 – 99.5 °F
Rectal: 36.6 – 38.0 °C 97.9 – 100.4 °F
ThermoScan: 35.8 – 38.0 °C 96.4 – 100.4 °F
Normal ThermoScan ranges by age:
0 – 2 years 36.4 – 38.0 °C 97.5 – 100.4 °F
3 – 10 years 36.1 – 37.8 °C 97.0 – 100.0 °F
11 – 65 years 35.9 – 37.6 °C 96.6 – 99.7 °F
> 65 years 35.8 – 37.5 °C 96.4 – 99.5 °F

If the probe has been fitted securely into the ear
canal during the complete measuring process,
a long beep will signal the end of the measuring
process. You can be assured to have taken an
accurate temperature reading. The result is shown
on the display (5).
If you take the temperature of another person, the
«ExacTemp» light (7) will be of help. It flashes
during the measuring process as long as the
probe is securely positioned, and lights up con-
tinuously when an accurate reading has been
taken.
4. If the probe has not been constantly placed in a
stable position in the ear canal, a sequence of
short beeps will sound, the «ExacTemp» light will
go out and the display will show an error message
(«POS» = position error).
5. For the next measurement, eject the used lens
filter (push ejector (4)) and put on a new, clean lens
filter.
IRT 4020: Clear the display by pushing the
«start» button once.
IRT 4520: Clear the display by pushing the
«I/O» button once.
Wait for the ready signal. Fit the probe snuggly
into the ear canal, then push the «start» button.
The Braun ThermoScan ear thermometer turns off
automatically after 60 seconds of inactivity.
The IRT 4520 can also be turned off by pressing
the «I/O» button for at least three seconds.
The display will shortly flash «OFF» and after
releasing the button it will go blank.
Temperature taking hints
• The right ear reading may differ from the reading
taken at the left ear. Therefore, always take the
temperature in the same ear.
• The ear must be free from obstructions or excess
earwax build-up to take an accurate reading.
• External factors may influence ear temperatures,
including when an individual has:
– been lying on one ear or the other
– had their ears covered
– been exposed to very hot or very cold tempera-
tures, or
– been recently swimming or bathing.

In these cases, remove the individual from the
situation and wait 20 minutes prior to taking a
temperature.
• Use the untreated ear if prescription ear drops or
other ear medications have been placed in the ear
canal.
Memory mode
The last temperature taken is stored in its memory
and will be automatically displayed when it is turned
on again. The display will show «MEM».
IRT 4520:
This model stores the last 8 temperature readings.
To display the stored readings, the thermometer
must be turned on. Then press the «I/O» button for
at least 1 second. The display shows the memory
number (e. g. MEM 1), and when releasing the
«I/O» button, the stored temperature for that memory
number is displayed, together with «MEM».
If «I/O» button is pressed too long, the thermometer
will be switched off. Each further pressing of the
«I/O» button displays the remaining memory numbers
(up to MEM 8).
MEM 1 is the latest reading, MEM 8 would be the
oldest.
The memory mode is left automatically after
displaying the oldest reading, or after pressing the
«I/O» button for at least 1 second.

Care and cleaning
The probe tip is the most delicate part of the
thermometer. It has to be clean and intact to ensure
accurate readings.
If the thermometer is ever accidentally used without
a lens filter, clean the probe tip as follows:
Very gently wipe the surface with a cotton swab or
soft cloth moistened with alcohol. After the alcohol
has completely dried out, you can put a new lens
filter on and measure. If the probe tip is damaged,
contact Braun.
Use a soft, dry cloth to clean the thermometer display
and exterior. Do not use abrasive cleaners. Never
submerge this thermometer in water or any other
liquid.
Store thermometer and lens filters in a dry location
free from dust and contamination and away from
direct sunlight.
Additional lens filters (LF 40) are available at most
stores carrying Braun ThermoScan or at Braun
Service Centers.
