4. How this thermometer measures Ear 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) can ensure the most accurate ear temperature. Measure-
ments taken from the surrounding tissue of the ear canal generate lower readings and may result in misdiag-
nosis of a fever.
To avoid an inaccurate measurement:
• First slip on a probe cover.
• Switch on the thermometer by pressing the O/I button.
• After one beep is heard (and the temperature scale icon is flashing), straighten the ear canal by gen-
tly pulling the middle of the ear back and up.
• Place the probe firmly into the ear canal, press the Start button and keep the probe in the ear until
the thermometer beeps to identify the completion of the measurement.
This thermometer has been clinically tested and proven to be safe and accurate when used in
accordance with its operating instruction manual.
