Measuring Temperature
•While in the forehead mode, a smil- ing face “ 
” will display to indicate a temperature lower than 38°C (100.4°F). If the temperature is equal to or higher than 38°C (100.4°F), you will see a frowning face “ 
” on the display, accompanied by one long beep followed by two short beeps (see Figures 7 and 8).
•The LCD displays “Lo” or “Hi” when the temperature measured is outside the ther- mometer’s sensory range (see Figures 9 and 10).
•“Err” appears if the operating temperature is outside the permissible range of 16°C to 35°C (60.8°F to 95°F) (see Figure 11).
•After one minute without use, the device automatically powers itself off to conserve battery life.
