• Accumulation of ear wax on the probe can result in less accurate
temperature readings or cross infection between users.
• It is essential that the probe is cleaned after every measure-
ment. Therefore, this device reminds the user to clean the probe
when turning off the device. «CLEAN ME» BK is displayed and
the probe LED light will flash for 3 seconds. For cleaning, follow
the instructions in the «Cleaning and Disinfecting» section.
• After cleaning the measuring sensor 1 with alcohol, wait 5
minutes 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 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 temper-
ature readings may be different from ear to ear.
• In the following situations it is recommended that three tempera-
tures 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.
• 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 150: 35.4 - 37.4 °C / 95.7 - 99.3 °F

7. Changing between Celsius and Fahrenheit

This thermometer can display temperature readings in either Fahr-
enheit or Celsius. To switch the display between °C and °F, simply
turn OFF the unit, press and hold the START button 3 for 5
seconds; after 5 seconds, the current measurement scale («°C» or
«°F» icon) will flash on the display AM. Change the measurement
scale between °C and °F by pressing the START button 3. When
the measurement scale has been chosen, wait for 5 seconds and
the unit will automatically enter the «ready for measuring» mode.

8. 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 AN: Press the M-button 6 to enter recall mode
when the power is off. The memory icon «M» will flash.
• Reading 1 - the last reading AO: Press and release the M-
button 6 to recall the last reading. Number «1» and a flashing
«M» are displayed.
• Reading 30 - readings in succession: Press and release the
M-button 6 consecutively to recall the last 30 readings in
succession.
Pressing and releasing the M-button 6 after the last 30 readings
have been recalled will resume the above sequence from reading 1.

9. Error Messages

• Measured temperature too high AP: Displays «H» when
measured temperature is higher than 100.0 °C / 212.0 °F.
• Measured temperature too low AQ: Displays «L» when
measured temperature is lower than 0 °C / 32.0 °F.
• Ambient temperature too high AR: Displays «H» when
ambient temperature is higher than 40.0 °C / 104.0 °F.
• Ambient temperature too low AS: Display «L» when ambient
temperature is lower than 10.0 °C / 50.0 °F.
• Error function display BT: The system has a malfunction.
• Blank display BL: Check if the battery has been loaded
correctly. Also check polarity (<+> and <->) of the battery.
• Flat battery indication BM: If only the «» icon is shown on
the display, the battery should be replaced immediately.

10. Cleaning and Disinfecting

Use an alcohol swab or cotton tissue moistened with alcohol (70%
Isopropyl) to clean the thermometer casing and the measuring
sensor. Ensure that no liquid enters the interior of the device. Never
