How to use your Braun ThermoScan?
1. To achieve accurate readings, make sure a new,
clean lens filter (1) is in place before each
measurement.
2. IRT 4020: Push the «start» button (8).
IRT 4520: Push the «I/O» button (6).
During an internal self-check, the display shows all
segments. Then the last temperature taken will be
displayed together with «MEM».
Wait for the ready signal beep and the ready symbol
in the display.
3. Fit the probe snuggly into the ear canal, then push
the «start» button (8).
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 continuously
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
• Always replace disposable lens filters to maintain
accuracy and hygiene.
• 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
temperatures, or
– been recently swimming or bathing.
