 Caution

1.  A person’s left and right ear canals are not necessarily 

symmetrical. This may cause different measurement 
results. Always take temperature readings in the same 
ear.

2.  A soiled probe lens will result in inaccurate measurement. 

Be sure to check that the probe lens is clean before use.

3.  Body temperature rises after vigorous exercise, a bath or 

shower, or eating. Wait at least 30 minutes before taking 
temperature readings.

4.  Do NOT use the ear thermometer when the ear canal is 

wet (after swimming, bathing, etc.).

5.  Let the ear thermometer stand at room temperature 

before use.

6.  It is important to know your normal temperature so you 

can compare it to the measurement result.

About Ear Thermometers

All objects radiate heat. To measure body temperature, this 
ear thermometer uses an infrared sensor incorporated in 
its probe to detect the heat radiated from the eardrum and 
the area around it. In general the ear canal (external auditory 
canal) of an infant is relatively straight.
As we grow older, it takes on some curvature, as shown 
in Fig. 2. It is important to point the probe lens of the ear 
thermometer toward the eardrum and its periphery inside 
the ear. To straighten the ear canal, gently pull on the outer 
ear in the direction of the rear of the head, as shown in Fig. 
3. Each ear canal has a slightly different shape, be sure to 
check it before taking temperature readings. Insert the probe 
straight into the ear canal, as shown in Fig. 4.
