Braun Thermoscan® 6 FAQs

A: ALWAYS replace the disposable lens filters with a genuine Braun lens filter to maintain accuracy and hygiene. The use of any other brand may alter the reading. The right ear measurement may differ from the measurement taken in 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:

  • Poor probe placement
  • Used lens filter
  • Dirty lens

In the cases below, wait 20 minutes prior to taking a temperature.

  • Extreme hot and cold room temperature
  • Hearing aid
  • Use the untreated ear if ear drops or other ear medications have been placed in the ear canal.

Use the ear that has been facing upwards, if an individual has been lying down on their side with an ear face down on a pillow.

A: This 3-year limited warranty applies to repair or replacement of product found to be defective in material or workmanship. This warranty does not apply to damage resulting from commercial, abusive, unreasonable use or supplemental damage. Defects that are the result of normal wear and tear will not be considered manufacturing defects under this warranty.

This will occur if the ambient temperature is not within the allowed operating range (50 - 104 °F or 10 - 40 °C.)  In order to resolve this, we would recommend you allow the thermometer to remain for 30 minutes in a room where the temperature is between 50 and 104 °F or 10 and 40 °C.

A: A flashing display indicates a system error. We suggest waiting 1 minute until the thermometer turns off by itself and then turns on again. If the problem persists, reset the thermometer by removing the batteries momentarily.

  1. Make sure the thermometer is turned off.
  2. Press and hold the power button. After about 3 seconds the display will show this sequence: °F / SET / °C / SET.
  3. Release the Power 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.

A: The last temperature taken is stored in the memory and will be automatically displayed for 5 seconds when it is turned on again.

A: Store thermometer and lens filters in a dry location free from dust and contamination and away from direct sunlight. Always store the thermometer with the protective cradle in place to prevent dirt and scratches from damaging the device.  

Do not store this thermometer in temperature extremes below -13 °F or over 131 °F or in excessive humidity (above 95% relative humidity).  

If thermometer is stored in a location that is cooler or warmer than where it will be used, allow it to acclimate to the room temperature for 10 minutes before taking the measurement.

A: To avoid inaccurate measurements ALWAYS use this thermometer with a new, clean lens filter attached. 

If the thermometer is accidentally used without a lens filter attached, clean the lens.  

The lens filter indicator will blink to signal one is needed. 

Attach a new lens filter by pushing the thermometer probe straight into the lens filter inside the box and then pulling out. 

Note: The Braun ThermoScan will not work unless a lens filter is attached. 

For the next measurement, press Eject button to remove and discard used lens filter, and put on a new, clean lens filter. For models without and eject button (ThermoScan 3 and 4), pull off lens filter and discard. 

A: The thermometer includes a convenient night light to illuminate the display in a dim environment. The light will turn on when you press any button. It will stay on until the thermometer is inactive for up to 15 seconds even after temperature is taken.

A: Temperature guidance helps you to better understand the meaning of your child's temperature with the color indicated on the display. The screen displays a green, yellow, or red backlight depending on the temperature reading.

It is important to note that a patient's temperature may be impacted by age, gender or medical condition, or by factors such as ambient temperature, time of day, medications taken or the temperature measurement site1.

A: ExacTemp® is a guidance system that confirms good position in the ear with a light and a beep to ensure accurate temperature measurement.

A: Yes, the Braun Thermoscan® 6 IRT6515 includes two AA batteries.


  1. Insert new batteries when the battery symbol appears on the display.
  2. Open the battery compartment. Remove the batteries and replace with new batteries, making sure the poles are in the right direction.
  3. Snap battery door into place.

A: Lens filters are included with all our Ear thermometers.  Please use a new lens filter after each use for an accurate reading.

A: Yes. Braun lens filters are universal across all our Ear thermometers & Braun lens filters are the only brand to ensure an accurate reading when used with Braun thermometers.

A: Yes, Braun disposable lens filters are BPA & latex free.

A: The ear is a good site for temperature measurement because it reflects the core temperature of the body1. Body temperature is regulated by the hypothalamus2., which shares the same blood supply as the tympanic membrane3. This means changes in core body temperature are usually detected sooner in the tympanic membrane than other areas. All Braun infrared ear thermometers feature ThermoScan® technology, which measure heat generated by the eardrum and surrounding tissue to give an accurate temperature on an easy to read digital display in seconds.

A: Gently wipe the surface of the probe tip with a cotton swab or soft cloth moistened with rubbing alcohol (70% Isopropyl).

A: Clinical research shows the definition of fever changes as newborns grow into children & children grow into adults. The Age Precision feature takes the guesswork out of temperature taking, allowing you to select the appropriate age setting - 0-3 months, 3-36 months or 36+ months.
