always consider other potentially occurring symptoms and
the patient's feedback. Calling a doctor or an ambulance is
advised if needed.

3. 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.
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 3 and keep the probe in the ear until the thermometer
beeps to signal the completion of the measurement.

4. Control Displays and Symbols

• All segments displayed 7: Press the ON/OFF button 4 to
turn on the unit; all segments will be shown for 1 second.
• Ready for measurement 9: When the unit is ready for
measurement, the «°C» or «°F» icon will keep flashing.
The probe LED light is activated for 10 seconds.
• Measurement complete AT: The reading will be shown on the
display 2 with the «°C» or «°F» icon; the unit is ready for the
next measurement, when the «°C» or «°F» icon is flashing again.
• Out-of-ear temperature indication AK: A crossed-ear-icon will
appear on the display 2 if the reading falls outside the range
32.0 ∼ 42.2 °C / 89.6 ∼ 108.0 °F.
• Low battery indicator AL: When the unit is turned on, the «»
icon will keep flashing to remind the user to replace the battery.
