Frequently Asked Questions - ThermoScan IRT 4020 BRAUN

How do I switch between Celsius and Fahrenheit?

With the thermometer off, press and hold the start button for about 3 seconds until the display shows "°C" / "SET" / "°F" / "SET". Release the button when the desired scale appears. A beep confirms the change.

How do I replace the batteries?

When the low battery symbol appears, open the battery compartment, replace with two 1.5V AA (LR06) batteries, ensuring correct polarity. Slide the door back until it clicks.

What does the error message "POS" mean?

"POS" indicates a position error. The probe was not securely placed in the ear canal. Clean the lens filter and reinsert the probe firmly, ensuring stable positioning during measurement.

Why is a lens filter necessary?

A clean lens filter ensures hygiene and accuracy. The thermometer cannot measure without a filter. Always use a new, genuine Braun ThermoScan Lens Filter (LF 40) for each reading.

How accurate is the Braun ThermoScan IRT 4020?

The accuracy is ±0.2°C for temperatures between 35.5°C and 42°C, and ±0.3°C outside this range. Clinical repeatability is ±0.14°C.

Can I use the thermometer in the rectum or mouth?

No, this thermometer is designed solely for ear temperature measurement. Using it in other body sites may produce inaccurate readings.

How do I clean the thermometer?

If used without a lens filter, gently wipe the probe tip with a cotton swab moistened with alcohol. For the display and exterior, use a soft, dry cloth. Never submerge in water or use abrasive cleaners.

What is the normal temperature range for different ages?

For children 0-2 years: 36.4-38.0°C; 3-10 years: 36.1-37.8°C; 11-65 years: 35.9-37.6°C; 65+ years: 35.8-37.5°C. These are ranges measured with ThermoScan.

What should I do if the thermometer gives an error like "HI" or "LO"?

These indicate the temperature is above 42.2°C (HI) or below 34°C (LO). Ensure a clean lens filter is attached and the probe is inserted correctly. If the reading persists, the ambient temperature may be out of range.

How long does it take to get a reading?

The measurement takes only a few seconds. Once the probe is securely placed, a long beep signals the end, and the temperature is displayed. The ExacTemp light indicates stable positioning.

The Braun ThermoScan thermometer has been carefully developed for accurate, safe and fast temperature measurements in the ear. The shape of the thermometer prevents it from being inserted too far into the ear canal to hurt the eardrum.

However, as with any thermometer, proper technique is critical to obtaining accurate temperatures. Therefore, read the use instructions carefully and thoroughly.

Important

• The operating ambient temperature range for this thermometer is 10 - 40 °C (50 - 104 °F).
• Do not expose the thermometer to temperature extremes (below -20 °C / -4 °F or over 50 °C / 122 °F) nor excessive humidity (> 95% RH).
• This thermometer must only be used with genuine Braun ThermoScan Lens Filters (LF 40). Never use this thermometer without a new, clean lens filter attached.
• Keep lens filters out of reach of children. • This thermometer is intended for household use only.
• Use of this thermometer is not intended as a substitute for consultation with your physician.

How does Braun ThermoScan work?

Braun ThermoScan measures the infrared heat generated by the eardrum and surrounding tissues. To avoid gross temperature differences, the sensor itself is brought to a temperature close to that of the human body. When the Braun ThermoScan is placed in the ear, it continuously monitors the infrared radiation. The measurement will be finished and the result is displayed, when an accurate reading can be assured.

Why measure in the ear?

The goal of thermometry is to measure core body temperature which is the temperature of the vital organs. Ear temperatures accurately reflect core body temperature, since the eardrum shares blood supply with the temperature control center in the brain, the hypothalamus. Therefore, changes in body temperature are reflected sooner and more accurately in the ear than at other sites.

• Axillary temperatures only measure skin temperature and therefore, are not a reliable indicator of core body temperature.
• Oral temperatures are influenced by drinking, eating and breathing.
• Rectal temperatures lag behind changes in core body temperature and there is a risk of cross-contamination.

Body temperature

Normal body temperature is a range. The following table shows that this normal range also varies by site. Therefore, readings from different sites should not be directly compared.

Normal ranges by site:

Axillary: 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 ThermoScan: 35.8 – 38.0 °C 96.4 – 100.4 °F

- As well, a person's normal temperature range tends to decrease with age. The following table shows normal ThermoScan ranges by age.

Normal ThermoScan ranges by age:

0 - 2 years 36.4 - 38.0 °C 97.5 - 100.4 °F 3 - 10 years 36.1 - 37.8 °C 97.0 - 100.0 °F 11 – 65 years 35.9 – 37.6 °C 96.6 – 99.7 °F

65 years 35.8 - 37.5 °C 96.4 - 99.5 °F

However, the range of normal also varies from person to person and fluctuates throughout the day. It is therefore important to determine your normal temperature range. This is easily done using Braun ThermoScan. Practice taking temperatures on yourself and healthy family members to determine their normal temperature ranges.

Note: When consulting your physician, communicate that the ThermoScan temperature is a temperature measured in the ear and if possible, note the individual's normal ThermoScan temperature range as additional reference.

How to use your Braun ThermoScan?

1. To achieve accurate readings, make sure a new, clean lens filter (1) is in place before each measurement.
2. IRT 4020: Push the "start" button (8). IRT 4520: Push the "I/O" button (6).

During an internal self-check, the display shows all segments. Then the last temperature taken will be displayed together with "MEM".

Wait for the ready signal beep and the ready symbol in the display.

1. Fit the probe snugly into the ear canal, then press the "start" button (8).

If the probe has been fitted securely into the ear canal during the complete measuring process, a long beep will signal the end of the measuring process. You can be assured to have taken an accurate temperature reading. The result is shown on the display (5).

If you take the temperature of another person, the "ExacTemp" light (7) will be of help. It flashes during the measuring process as long as the probe is securely positioned, and lights up continuously when an accurate reading has been taken.

1. If the probe has not been constantly placed in a stable position in the ear canal, a sequence of short beeps will sound, the "ExacTemp" light will go out and the display will show an error message ("POS" = position error).
2. For the next measurement, eject the used lens filter (push ejector (4)) and put on a new, clean lens filter. IRT 4020: Clear the display by pressing the "start" button once.

IRT 4520: Clear the display by pressing the "I/O" button once.

Wait for the ready signal. Fit the probe snugly into the ear canal, then press the "start" button.

The Braun ThermoScan ear thermometer turns off automatically after 60 seconds of inactivity. The IRT 4520 can also be turned off by pressing the "I/O" button for at least three seconds. The display will shortly flash "OFF" and after releasing the button it will go blank.

Temperature taking hints

• Always replace disposable lens filters to maintain accuracy and hygiene. - The right ear reading may differ from the reading taken at the left ear. Therefore, always take the temperature in the same ear. - The ear must be free from obstructions or excess earwax build-up to take an accurate reading. - External factors may influence ear temperatures, including when an individual has: – been lying on one ear or the other - had their ears covered – been exposed to very hot or very cold temperatures, or – been recently swimming or bathing.

In these cases, remove the individual from the situation and wait 20 minutes prior to taking a temperature.

Use the untreated ear if prescription ear drops or other ear medications have been placed in the ear canal.

Memory mode

The last temperature taken is stored in its memory and will be automatically displayed when it is turned on again. The display will show «MEM».

IRT 4520;

This model stores the last 8 temperature readings. To display the stored readings, the thermometer must be turned on. Then press the «I/O» button for at least 1 second. The display shows the memory number (e.g. MEM 1), and when releasing the «I/O» button, the stored temperature for that memory number is displayed, together with «MEM». If «I/O» button is pressed too long, the thermometer will be switched off. Each further pressing of the «I/O» button displays the remaining memory numbers (up to MEM 8). MEM 1 is the latest reading, MEM 8 would be the oldest. The memory mode is left automatically after displaying the oldest reading, or after pressing the «I/O» button for at least 1 second.

Changing the temperature scale

Your Braun ThermoScan is shipped with the Celsius (°C) temperature scale activated. If you wish to switch to Fahrenheit (°F) and/or back from Fahrenheit to Celsius, proceed as follows:

(1) Make sure the thermometer is turned off.

(2) Press and hold down the «start» button (IRT 4020) or the «I/O» button (IRT 4520). After about 3 seconds the display will show this sequence: «°C» / «SET» / «°F» / «SET» ...

(3) Release the «start» button / «I/O» button when the desired temperature scale is shown. There will be a short beep to confirm the new setting, then the thermometer is turned off automatically.

Care and cleaning

The probe tip is the most delicate part of the thermometer. It has to be clean and intact to ensure accurate readings.

If the thermometer is ever accidentally used without a lens filter, clean the probe tip as follows: Very gently wipe the surface with a cotton swab or soft cloth moistened with alcohol. After the alcohol has completely dried out, you can put a new lens filter on and measure. If the probe tip is damaged, please contact your authorized local service centre.

Use a soft, dry cloth to clean the thermometer display and exterior. Do not use abrasive cleaners. Never submerge this thermometer in water or any other liquid.

Store thermometer and lens filters in a dry location free from dust and contamination and away from direct sunlight.

Additional lens filters (LF 40) are available at most stores carrying Braun ThermoScan.

For more information, please contact your authorized local Service Centre.
