[. . . ] The body temperature measured in the ear may differ from the measurement under the armpit or in the mouth or rectum. Therefore, they cannot merely be compared. Take the temperature periodically to determine the reading with this instrument when body temperature is normal, then use that as the basis for comparison with any measurement taken when you suspect a fever. Do NOT use this thermometer for measurements other than body temperature. [. . . ] A short, double beep tells you that measurement is completed. The measurement result will flash on the display if the ambient (room) temperature is 35 °C or higher which means the measurement is not completed. In such a case, take the following steps to measure again. Press the switch, and turn the power off.
