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.
