The temperature taken with this infrared Thermometer is different than when taken with another thermometer. 


1) Switch thermometer to "human" mode and not "object" mode.  Use the M button to change the measurement mode. 

2) Make sure the thermometer is about 1/2 away from the forehead before taking a measurement.

3) Check page 5 of the instruction manual about temperature differences when taken on the forehead, ear or with a stick thermometer.
