[. . . ] Ear temperatures accurately reflect core body temperature, since the eardrum shares blood supply with the temperature control center in the brain, the hypothalamus. Therefore, changes in body temperature are reflected sooner and more accurately in the ear than at other sites. ⷠAxillary temperatures only measure skin temperature and therefore, are not a reliable indicator of core body temperature. ⷠOral temperatures are influenced by drinking, eating and breathing. [. . . ] ⷠUse the untreated ear if prescription ear drops or other ear medications have been placed in the ear canal. The last temperature taken is stored in its memory and will be automatically displayed when it is turned on again. Then press the «I/O» button for at least 1 second. 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). The memory mode is left automatically after displaying the oldest reading, or after pressing the «I/O» button for at least 1 second. Your Braun ThermoScan is shipped with the Celsius (°C) temperature scale activated. If you whish 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. 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. Store thermometer and lens filters in a dry location free from dust and contamination and away from direct sunlight. Take care that the positioning of the probe is correct and remains stable. Allow the thermometer to remain in a room for 30 minutes where the temperature is between 10 and 40 °C or 50 and 104 °F. Ambient temperature is not within the allowed operating range (10 ­ 40 °C or 50 ­ 104 °F). Temperature taken is not within typical human temperature range (34 ­ 42. Make sure a new, clean lens filter is attached and thermometer is properly inserted. LO = too low System error ­ self-check display flashes continuously and will not be followed by the ready beep and the ready symbol. [. . . ] It is therefore important to determine your and your family members' normal temperature ranges. Practise taking temperatures on yourself and healthy family members to determine their normal temperature ranges. Note: When consulting your physician, communicate that the ThermoScan temperature is a temperature measured in the ear and if possible, note the individual's normal ThermoScan temperature range as an additional reference. How to use Braun ThermoScan To achieve accurate readings, make sure a new, clean lens filter is in place before each measurement. [. . . ]
