•The operating ambient temperature range for this thermometer is 50
•Do not expose the thermometer to temperature extremes (below
•This thermometer must only be used with genuine Braun ThermoScan Lens Filters.
•To avoid inaccurate measurements always use this thermometer with a new, clean lens filter attached.
•If the thermometer is accidentally used without a lens filter attached, clean the lens (see «Care and cleaning»).
•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 consultation with your physician.
How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat generated by the eardrum and surrounding tissues. To help to avoid inaccurate temperature measurements, the probe tip is warmed to a temperature close to that of the human body. When the Braun ThermoScan is placed in the ear, it continuously monitors the infrared energy.
The measurement is finished and the result displayed when the thermometer detects that an accurate temperature measurement has been taken.
Why measure in the ear?
The goal of thermometry is to measure core body temperature1 which is the temperature of the vital organs. Ear temperatures accurately reflect core body temperature2, since the eardrum shares blood supply with the temperature control center in the brain3, the hypothalamus. Therefore, changes in body temperature are reflected sooner in the ear than at other sites.
•Axillary temperatures measure skin temperature and therefore, may not be a reliable indicator of core body temperature.
•Oral temperatures are influenced by drinking, eating and mouth breathing.
•Rectal temperatures often lag behind changes in core body temperature and there is a risk of
