for each measurement to prevent infection. Only Microlife branded

probe covers can ensure that you get an accurate measurement.

• Never immerse this device in water or other liquids. For

cleaning please follow the instructions in the «Cleaning
and Disinfecting» section.

• Do not use the device if you think it is damaged or notice
anything unusual.

• Never open the device.

• Earwax in the ear canal may cause a lower temperature reading.
Therefore it is important to ensure the subject’s ear canal is clean.

• This device comprises sensitive components and must be trea­ted with caution. Observe the storage and operating conditions
described in the «Technical Specifications» section.

• Protect it as well as the probe covers from:

- extreme temperatures

- impact and dropping

- contamination and dust

- direct sunlight

- heat and cold

• If the device is not going to be used for a prolonged period the
batteries should be removed.

• Ensure that children do not use the device unsupervised; some
parts are small enough to be swallowed.

• The function of this device may be compromised when used
close to strong electromagnetic fields such as mobile phones or
radio installations and we recommend a distance of at least 1m.
In cases where you suspect this to be unavoidable, please verify
if the device is working properly before use.

4. How this Ear 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) 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:

• 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 gently 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
signal 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.

7. Directions for Use

Important: Prior to every measurement, fit a new undamaged Probe

Cover on the measuring probe. Failure to do so may result in incorrect
temperature measurement.

1. Press the O/I button. The display is activated
to show all segments for 2 seconds.

2. The last measurement reading will automati­cally be shown on the display for 2 seconds
with the «M» icon.

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

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 (max. 1 sec.)
and immediately press the START button.
Release the button and wait for the beep
sound. This is the indication that confirms
the end of measurement.

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

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

EN

Replace the probe cover after each measurement. To do this, please
follow the instruction in point 6 «How to Reload a New Probe Cover».

• 10 short beeps and a red LCD backlight alert the patient that he/
she 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 child or adult,
it is best to stand behind and slightly to the side of the patient.

• 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:

1) New born infants in the first 100 days.

2) Children under three years of age with a compromised immune
system and for whom the presence or absence of fever is critical.

3) 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.

4) If the measurement is surprisingly low.

8. Changing from Fahrenheit to Celsius and vice-versa

The thermometer can display temperature measurements in either
Fahrenheit or Celsius. To switch the display between °C and °F, simp­ly turn OFF the unit, press and hold the START button for 5 seconds
until «---» and the flashing «°C» or «°F» icon is shown on the LCD.
Switch the measurement scale between °C and °F by pressing the
START button again. When the measurement scale has been chosen,
wait for 5 seconds and the unit will enter the ready for measuring
mode automatically.

9. How to recall 12 readings in Memory Mode

This thermometer can recall the last 12 readings. To recall please
follow sequence.

LCD Display Display

Pressing and releasing the START button after the last 12 readings
have been recalled will resume the above sequence from reading 1.

10. Cleaning and Storage

Use an alcohol swab or cotton tissue
moistened with alcohol (70% Isopropyl)
to clean the thermometer casing and the
measuring probe. Ensure that no liquid
enters the interior of the thermometer.
Never use abrasive cleaning agents, thinners
or benzene for cleaning and never immerse the device in water
or other cleaning liquids. Take care not to scratch the surface of
the probe lens and the display. Remove the battery from the device if
it is not required for extended periods of time in order to avoid dama­ge to the thermometer resulting from a leaking battery.
