WARNING: The measurement results given by this device is not a diagnosis. It is not replacing the need for the consultation of a physician, especially if not matching the patient’s symptoms. Do not rely on the  measurement result only, always consider other potentially occurring symptoms and the patient’s feedback. Calling a doctor or an ambulance is advised if needed.

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. Fit a new Microlife branded and undamaged probe cover 29 on the measuring sensor 1.
2. Switch on the thermometer by pressing the START/IO button 6.
3. 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.
4. Place the probe 1 firmly into the ear canal. «Good» will be displayed with a short beep to confirm the device has detected the correct position. Press the START/IO  utton 6 and keep the probe in the ear until the thermometer beeps to signal the completion of the measurement.

Control Displays and Symbols

• All segments displayed 7: Press the START/IO button 6 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 and will keep flashing.
• Correct position indication 10 : The probe LED light will stop flashing (stays illuminated) and «good» will be displayed on the LCD, when the measuring sensor detects an appropriate position.
• Measurement complete 11: 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.
• Low battery indicator 15: When the unit is turned on, the icon will keep flashing to remind the user to replace the battery.

Directions for Use

Important: Before each measurement, fit a new undamaged probe cover 29 on the measuring sensor 1. Failure to do so will result in incorrect temperature measurements. How to correctly fit a new probe cover 29 is pictured at the beginning of this instruction 30.

1. Press the START/IO button 6. The display 2 is activated to show all segments for 1 second.

2. When the «°C» or «°F» icon is flashing, a beep sound is heard and the thermometer is ready for measuring 9.

3. The probe LED light is activated and will keep flashing.

4. Straighten the ear canal by pulling the ear up and back to give a clear view of the eardrum.
   • For children under 1 year; pull the ear straight back.
   • For children of 1 year to adult; pull the ear up and back.
   Also refer to the short instructions at the front.

5. While gently pulling the ear, insert the probe snugly into the ear canal.

6. The probe LED light will stop flashing (stays illuminated) and «good» will be displayed on the LCD, when the measuring sensor detects an appropriate position.

7. Immediately press the START/IO button 6. Release the button and wait for the beep sound. This indicates the end of the measurement.

8. Remove the thermometer from the ear canal. The display shows the measured temperature 11.

9. Press and release the cover ejector 4 to remove the used probe cover before starting a new measurement. Fit a new undamaged probe 29 cover on the measuring sensor 1.

10. For the next measurement wait until the «°C»/«°F» icon is flashing and follow steps 5 – 7 above.

11. Press and hold the START/IO button 6 for 3 seconds to turnoff the device; otherwise the device will automatically switch ofafter approx. 60 seconds.

NOTE:

• Patients and thermometer should stay in similar room condition for at least 30 minutes.

• To ensure accurate readings, wait at least 30 sec. after 3-5continuous measurements.

• It is essential that a new undamaged probe cover 29 is used for each measurement. Therefore, this device remindsthe user to take off the used probe cover when turning off the device. The «probe cover» icon 13 is displayed and the probeLED light will flash for 3 seconds. For cleaning, follow the instructions in the «Cleaning and disinfecting» section.

• The device detects if there is no probe cover placed on the measuring sensor when a measurement is performed; a probecover icon 13 and a red LCD backlight will alert the patient accordingly.

• After cleaning the measuring sensor 1with alcohol, wait 5minutes before taking the next measurement, in order to allow the thermometer to reach its operating reference
  temperature.

• 10 short beeps and a red LCD backlight alert the patient that heshe may have a temperature equal to or higher than 37.5 °C.

• For an infant, it is best to have the child lying flat with his/her head sideways so the ear is facing upwards. For an older childor adult, it is best to stand behind and slightly to the side of thepatient.

• Always take the temperature in the same ear, since the temperature readings may be different from ear to ear.

• In the following situations it is recommended that three temperatures in the same ear be taken and the highest one taken as the reading:
  – New born infants in the first 100 days.
  – Children under three years of age with a compromised immune system and for whom the presence or absence of fever is critical.
  – When the user is learning how to use the thermometer for the first time until he/she has familiarized himself/herself with the device and obtains consistent readings.
  – If the measurement is surprisingly low.

• Don’t take a measurement while or immediately after nursing a baby.

• Don’t use the thermometer in high humidity environments.

• Patients should not drink, eat or exercise before/while taking the measurement.

• Doctors recommend rectal measurement for newborn infants within the first 6 months, as all other measuring methods might lead to ambiguous results.

• Readings from different measuring sites should not be compared as the normal body temperature varies by measuring site and time of day, being highest in the evening and lowest about one hour before waking up.

• Normal body temperature ranges:
  – Axillar: 34.7 – 37.3 °C / 94.5 – 99.1 °F
  – Oral: 35.5 – 37.5 °C / 95.9 – 99.5 °F
  – Rectal: 36.6 – 38.0 °C / 97.9 – 100.4 °F
  – Microlife IR 310: 35.4 – 37.4 °C / 95.7 – 99.3 °F

Changing between Celsius and Fahrenheit

This thermometer can display temperature readings in either Fahrenheit or Celsius 16.

• To switch the display between °C and °F, press and hold the M- button 3 for 5 seconds when device is power off; «°C»/«°F» icon is shown on the display.
• Press the M-button 3 to change the measurement scale between °C and °F .
• When the measurement scale has been chosen, press the START/IO button 6 to enter the «ready for measuring» mode; otherwise the device automatically switches to ready for measuring after 5 seconds 9.

How to recall 30 readings in Memory Mode

This thermometer can recall the last 30 readings with a record of both time and date.

• Recall mode 30: Press the M-button 3 to enter recall mode when the power is off. The memory icon «M» will show.
• Reading 1 – the last reading 18: Press and release the Mbutton 3 to recall the last reading. Number «1» and a flashing «M» are displayed.

Pressing and releasing the M-button 3 after the last 30 readings have been recalled will resume the above sequence from reading 1.
