If the probe has been securely inserted into
the ear canal during the complete measuring
process, a long beep will signal the end of the
measuring process. The thermometer detects
that an accurate temperature measurement has
been taken. The result is shown on the display (5).
If you take the temperature of another person,
the «ExacTemp» light (7) can be of help. It flashes
during the measuring process when the probe is
securely positioned, and lights up continuously
when the thermometer detects that an accurate
measurement 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 and release 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 measurement may differ from the
measurement taken in 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
