The lens filter indicator will blink 
to signal one is needed.
To achieve accurate 
measurements, make sure a 
new, clean lens filter is in place 
before each measurement.
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.
The thermometer is ready to take a temperature when the display looks like the images below.
Parents/guardians should call the pediatrician upon noticing any unusual sign(s) or symptom(s). For example, a 
child who exhibits irritability, vomiting, diarrhea, dehydration, seizure, changes in appetite or activity, even in the 
absence of fever, or who exhibits a low temperature, may still need to receive medical attention.
People who are on antibiotics, analgesics, or antipyretics should not be assessed solely on temperature 
readings to determine the severity of their illness.
Temperature elevation may signal a serious illness, especially in neonates and infants, or in adults who are 
old, frail, or have a weakened immune system. Please seek professional advice immediately when there is a 
temperature elevation and if you are taking temperature on:
• Neonates and infants under 3 months (Consult your physician immediately if the temperature exceeds 
99.4 °F or 37.4 °C).
• Patients over 60 years of age (Fever may be blunted or absent in older patients).
• Patients having diabetes mellitus or a weakened immune system (e.g., HIV positive, cancer chemotherapy, 
chronic steroid treatment, splenectomy)
• Patients who are bedridden (e.g., nursing home patient, stroke, chronic illness, recovering from surgery)
• A transplant patient (e.g., liver, heart, lung, kidney). 
This thermometer contains small parts that can be swallowed or produce a choking hazard to children. 
Keep out of reach of children under 12 years. 
How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat generated by the eardrum and 
surrounding tissues. To help avoid inaccurate temperature measurements, the probe 
tip is warmed to a temperature close to that of the human body. When the Braun 
ThermoScan is placed in the ear, it continuously monitors the infrared energy. The 
measurement is finished and the result displayed when the thermometer detects 
that an accurate temperature measurement has been taken.

During an internal self-check, the display shows all 
segments. Then the last temperature taken will be 
displayed for 5 seconds. 
Body temperature
Normal body temperature is a range. It varies by site of measurement, and it tends to 
decrease with age. It also varies from person to person and fluctuates throughout the day. 
Therefore, it is important to determine normal temperature ranges. This is easily done using 
Braun ThermoScan. Practice taking temperatures on yourself and healthy family members 
to determine the normal temperature range.
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. 
Why measure in the ear?
The goal of thermometry is to measure core body temperature
1
which is the
temperature of the vital organs. Ear temperatures accurately reflect core body 
temperature
2
, since the eardrum shares blood supply with the temperature control
center in the brain
3
, the hypothalamus. Therefore, changes in body temperature
are reflected sooner in the ear than at other sites. Axillary temperatures measure 
skin temperature and may not be a reliable indicator of core body temperature. 
Oral temperatures are influenced by drinking, eating and mouth breathing. Rectal 
temperatures often lag behind changes in core body temperature and there is a 
risk of cross-contamination.

Fit the probe snuggly into the ear canal, then push 
and release the Start button
.
ExacTemp light will pulse while temperature is in progress. 
The light will remain solid for 3 seconds to indicate that a 
successful temperature reading has been achieved.
NOTE: If the probe has been properly inserted into the ear canal 
during the measurement, a long beep will sound to signal the 
completed measurement. 
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).

The confirmation beep indicates that an accurate 
temperature measurement has been taken. The 
result is shown on the display.
For the next measurement, press Eject button to 
remove and discard used lens filter, and put on a new, 
clean lens filter.
The Braun ThermoScan ear thermometer turns off 
automatically after 60 seconds of inactivity. 
The thermometer can also be turned off by 
pressing the Power button
.
The display will briefly flash OFF and it will go blank.

Temperature taking hints
Always replace disposable lens filters to maintain accuracy and hygiene. 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:
Factor
Yes affects
Poor probe placement
Used lens filter
Dirty lens
In the cases below, wait 20 minutes prior to taking a temperature.
