4. How This Thermometer Measures 

Temperature

This thermometer measures infrared energy radiated from the eardrum and the 
surrounding tissue. This energy is collected through the lens and converted to 
a temperature value. The measured reading obtained directly from the eardrum 
(Tympanic Membrane) ensures the most accurate ear temperature.

Measurements taken from the surrounding tissue of the ear canal generate 
lower readings and may result in misdiagnosis of fever.

5. Setting Date And Time

1.  When using the Ear Thermometer for the first time please remove the plastic 

strip located in the battery compartment.

START

 button
