How to use the Forehead Thermometer:
Hold the thermometer firmly at both ends and press flat against the middle of a dry forehead.
Hold in place for at least 15 seconds.
Read the thermometer while it is on the forehead. (Use a mirror to read the thermometer on yourself). Look at the boxes and check the colour.
Green indicates the correct temperature.
If the only colours showing are blue and tan the temperature is between the two.
