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.
Changing the temperature scale
Your Braun ThermoScan is shipped with the Celsius
(°C) temperature scale activated. If you wish to
switch to Fahrenheit (°F) and/or back from
Fahrenheit to Celsius, proceed as follows:
(1) Make sure the thermometer is turned off.
(2) Press and hold down the «start» button (IRT
4020) or the «I/O» button (IRT 4520). After about
3 seconds the display will show this sequence:
«°C» / «SET» / «°F» / «SET» ...
(3) Release the «start» button / «I/O» button when
the desired temperature scale is shown. There
will be a short beep to confirm the new setting,
then the thermometer is turned off automatically.
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, please contact your
authorized local service centre.
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.

local service centre.
