• Never immerse this instrument in water or other
liquids. For cleaning please follow the instruc-
tions in the «Cleaning and Disinfecting» section.
• Do not use the instrument if you think it is damaged or
notice anything unusual.
• Never open the instrument.
• Earwax in the ear canal may cause a lower temperature
reading. Therefore it is important to ensure the subject's
ear canal is clean.
• A basic physiological effect called vasoconstriction can
occur in the early stages of fever, resulting in a cool skin
effect. The recorded temperature using a forehead ther-
mometer can, therefore, be unusually low.
• If the measurement result is not consistent with the
patient's finding or unusually low, repeat the measure-
ment every 15 minutes or double check the result by
another core body temperature measurement.
• This instrument comprises sensitive components and
must be treated with caution. Observe the storage and
operating conditions described in the «Technical Specifi-
cations» section.
• Ensure that children do not use the instrument unsuper-
vised; some parts are small enough to be swallowed.

• Protect it from:
− extreme temperatures
− impact and dropping
− contamination and dust
− direct sunlight
− heat and cold
• If the instrument is not going to be used for a prolonged
period the battery should be removed.
WARNING: Use of this instrument is not intended as
a substitute for consultation with your physician. This
instrument is NOT waterproof so do not immerse in
liquids.
3. How this Thermometer measures Temper-
ature
This thermometer measures forehead and ear temperature.
Forehead measurement
This thermometer measures infrared energy radiated from
the skin above the eyebrow area and the surrounding
tissue. This energy is collected through the lens and
converted to a temperature value.
Temperature readings obtained by scanning above the
eyebrow area will provide the greatest accuracy.
Ear measurement
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 misdiag-
nosis of fever.
To avoid an inaccurate measurement:
1. Switch on the thermometer by pressing the ON/OFF
button 4.
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 1 firmly into the ear canal, press the
START button 2 and keep the probe in the ear until the
thermometer beeps to signal the completion of the
measurement.
