• Never open the instrument.
• Earwax in the ear canal may cause a lower temperature reading. Therefore it is impor-
tant to ensure the subject's ear canal is clean.
• This instrument comprises sensitive components and must be treated with caution.
Observe the storage and operating conditions described in the “Technical Specifications” sec-
tion.
• Protect it from:

sultation with your physician.
This instrument is NOT waterproof! NEVER immerse into liquids.
3. How this Ear 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) can ensure the
most accurate ear temperature. Measurements taken from the surrounding tissue of the ear
canal generate lower readings and may result in misdiagnosis of a fever.
To avoid an inaccurate measurement:
1. Switch on the thermometer by pressing the ON/OFF button.
2. After one beep is heard (and the temperature scale icon is flashing), straighten the ear
canal by gently pulling the middle of the ear back and up.
3. 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.
