Find some answers to the most frequently asked questions about your non-contact forehead thermometer. Turn on the unit by pressing and releasing the STAND-BY (ON / MEM) button once. The backlight will turn on and the startup sequence will begin. When you turn on the unit, you will see the icon for measuring your child's forehead temperature on the screen and you will hear 2 beeps. This is the default mode. Hold the thermometer at a maximum distance of 4 cm from the center of your child's forehead, just between the eyebrows, and hold it steady. Press the START button and hold the thermometer in place until you hear a final beep. You should now be able to read your child's temperature on your LCD screen. Wait for the forehead icon to stop flashing before taking the next temperature measurement. Remember that if you are concerned about your child's health, you should see a doctor. Even without a fever, your child may still need medical attention.
