Thank you for  
purchasing the  
Braun ThermoScan  
Instant Thermometer  
Unlike other thermometers that must be held  
in place for several minutes, the Braun  
ThermoScan Instant Thermometer takes a  
temperature in just one second. It takes a  
“picture“ of the infrared heat given off by the  
ear drum and surrounding tissue, calculates,  
and displays an ear temperature on the digital  
readout.

Lens filters are located inside the thermometer  
storage cover. Remove the box from the cover  
and open the box of lens filters by completely  
removing top of box (Figure 4a). You may  
return the box to the cover for convenient  
storage (Figure 4b).  
The Braun ThermoScan Instant Thermometer  
displays ear temperature readings, which  
frequently cannot be compared directly to  
temperatures taken at the same time at  
another site. This is because the temperature  
measured at the ear with the Braun  
ThermoScan Thermometer more closely  
reflects any rapid changes occurring with the  
internal (core) body temperature.

The thermometer is shipped with a lens filter in  
place. To install a new lens filter, remove the  
one in place, then take a new one from the box  
and holding it by its edges, slide it onto the  
lens until it is snug and snaps in place.  
Temperatures taken in the ear canal tend to  
reflect changes in internal body temperature  
sooner than oral, rectal or axillary (armpit)  
because the eardrum shares blood supply  
with the temperature control center in the  
brain. Oral temperatures are influenced by  
eating, drinking, smoking, rapid breathing,  
thermometer placement or the inability of the  
person to close their mouth completely.  
Axillary temperatures have not been found to  
be accurate indicators of core temperatures  
except in newborns.  
Figure 4  
Caution: Do not touch the tip of the lens or  
lens filter when installing.  
With a new lens filter in place, attach the  
storage cover to the thermometer to protect  
the lens from damage and dirt. Place the lens  
end of the thermometer into the storage cover  
first matching the indent in front of the  
activation button with the corresponding tab  
inside the cover (Figure 5a), then snap the  
opposite ends together (Figure 5b). To  
remove the unit from the storage cover,  
reverse this procedure.  
Temperature changes are also seen sooner  
when measured in the ear canal. Studies  
show that rectal temperatures “lag“ behind  
internal (core) body temperatures, especially  
during periods of rapid warming and cooling,  
as when you have a fever. This is due to the  
poor blood supply in this area, insulating  
effects of stool, and the presence of heat  
producing microorganisms located there.  
Note: Always use and store the thermo-  
meter with a new lens filter attached.  
Apply label to storage cover as indicated  
(Figure 5c).

Body temperature  
measurement  
Normal body temperature is a “range“, not a  
single point, as temperature varies from  
person to person. A person’s temperature can  
rise with excessive clothing, hot weather or  
accelerated activity (such as crying or  
exercise). In order to observe these naturally  
occurring variations and determine the normal  
temperature range for each member of your  
family, practice taking temperatures on  
yourself and healthy family members at  
different times of the day to determine their  
“baseline“ temperature. The normal range for  
ear temperatures taken with the Braun  
ThermoScan Instant Thermometer is from  
35.8°C (96.4°F) to 38.0°C (100.4°F) for all  
ages.  
1. Remove the thermometer from its storage  
cover. If stored properly, a new lens filter will  
already be in place. (See procedure on  
page 7.) Do not use thermometer without  
lens filter attached.

Instant Thermometer  
2. Depress the on-button  
that is located  
directly below the LCD (liquid crystal  
display) to turn the power on. (See Figure 1)  
• All segments on the LCD-display (Figure  
6) will be shown for two seconds to  
indicate a fully functional display.  
• The display will indicate

that the thermometer is ready to take a  
temperature (Figure 7). If no temperature  
is taken within two minutes, the ther-  
mometer will automatically shut off.  
Normal body temperature also varies with  
age. We have the highest temperatures when  
we are younger. About our eleventh year,  
body temperature begins to decrease  
gradually. The elderly population has the  
lowest body temperatures. For your reference,  
the following chart shows normal ear

3. Stabilise the head. In infants, this is best  
achieved by laying them flat with the head  
rotated so the ear is up.  
Figure 6  
temperature ranges by ages groups for the  
Braun ThermoScan Instant Thermometer:  
4. Perform an ear tug and position the  
thermometer. In order to take an accurate  
temperature, the thermometer must be  
positioned correctly in the ear. In addition,  
an “ear canal straightening“ technique must  
be used to straighten the natural bend of the  
canal and ensure that the thermometer has  
a clear view of the eardrum.  
• If you are right handed, hold the  
thermometer in the right hand and take  
the temperature in the right ear. If you are  
left handed, hold it in the left hand and  
use the left ear. This will help ensure  
proper placement.  
• Perform an “ear tug“ by using your free  
hand to grasp the outer edge of the top  
half of the ear and follow the steps in the  
chart below. To take your own temper-  
ature, an ear tug is best achieved by  
wrapping your free hand around the back  
of your head and grasping your ear from  
behind.

When consulting your physician about fever,  
remember to communicate that this is an ear  
temperature, referrring to the appropriate ear  
temperature range in the chart above. Also,  
note the individual’s “baseline“ temperature as  
an additional reference point.  
Continue pulling the ear until you are  
finished taking the temperature.

No more than three readings should be  
taken consecutively in the same ear since  
repeatedly inserting the thermometer into  
the ear canal can lower the reading.  
Ear tug and  
positioning  
technique  
Children unter 1 year  
• Ear Tug Gently but firmly pull ear straight  
back (Figure 8a).  
• Positioning Approach the ear from behind  
the child. Place the lens at the opening of  
the ear canal. Using a slight back and forth  
rocking motion, gently insert the ther-  
mometer, pointing the lens toward the  
opposite eye. Gently insert the lens as far  
as possible until the ear canal is fully sealed  
off (Figure 8c).  
6. When the unit is removed from the ear, the  
temperature will be shown on the display  
(Figure 9) until another temperature is taken  
or the unit powers down. The thermometer  
is ready to take a new temperature when  
(ready) appears on the screen along with  
the last temperature reading (Figure 10). To  
help ensure accuracy, you must change the  
lens filter after each reading. Inspect the  
lens whenever you replace a lens filter. Two  
minutes after the final temperature reading,  
the thermometer will automatically turn itself  
of to conserve battery power.  
Children 1 Year to Adult  
• Ear Tug Gently but firmly pull ear up and  
back (Figure 8b).  
Figure 9  
• Positioning Approach the ear from behind  
the person. Place the lens at the opening of  
the ear canal. Using a slight back and forth  
rocking motion, gently insert the ther-  
mometer, pointing the lens slightly in front of  
the opposite eye. Insert the thermometer as  
far as possible until the ear canal is fully  
sealed off (Figure 8c).  
7. Before storing the thermometer in its  
storage cover, change the lens filter (see  
page 17 “Care and Cleaning“) and check to  
make sure the filter is intact with no visible  
scratches or holes. If a lens filter is  
damaged, dispose of it and replace it with a  
new one. Additional lens filters (LF 40) are  
available at most stores carrying Braun  
ThermoScan Instant Thermometers, or  
contact Braun for a store near you.  
5. After the thermometer is correctly  
positioned, press the “Activation“ button  
with the index finger and hold fully  
depressed for one second.  
Figure 10  
NOTE: In the following situations, it is  
recommended that you take three  
temperatures in the same ear. If they  
differ, use the highest reading.  
(1) Infants in the first 90 days of life.  
(2) Children under trhee years of age  
who have a condition such as a  
compromised immune system and for  
whom the presence or absence of fever  
is critical.

taking hints  
• It is important to use an ear tug, point the  
thermometer lens toward the eardrum and  
gently insert far enough into the ear canal to  
obtain an accurate reading.  
Troubleshooting  
The Braun ThermoScan Instant Thermometer has been designed to  
provide feedback to ensure proper usage and accurate temperature taking.  
In many cases this means that instead of displaying a temperature that is  
not meaningful, a message will be displayed that will help you take  
corrective action. These messages are outlined below:  
• When taking a temperature on another  
person, it may be more difficult to  
consistently position the thermometer in  
their ear. If the person whose temperature  
is to be taken is old enough, ask for  
assistance in the positioning process.

Lens Tip  
Care and cleaning  
LCD-Display Situation  
The activation button was  
Solution  
• The lens tip is the most delicate part of the  
thermometer. It is covered with a soft, thin  
membrane which forms a surface that is  
transparent to heat waves. To ensure  
accuracy, it is very important to keep the  
lens clean and intact, and to always keep a  
clean, new lens filter attached. Fingerprints,  
ear wax, dust and other soiling compounds  
reduce ransparency of the lens, resulting in  
lower temperature readings. Remember:  
always store the thermometer in its cover  
when not in use.  
• Inspect the lens whenever you replace a  
lens filter. To clean the lens, very gently  
wipe the surface with a cotton swab or soft  
cloth moistened with alcohol or mild soap  
and warm water (Figure 11). After cleaning,  
allow at least 45 minutes drying time before  
reattaching a lens filter and taking tem-  
peratures. If the lens is damaged, contact

Lens Filters  
• Replace lens filter after each use. Make  
sure that the new lens filter is not damaged.  
• Keep lens filters out of direct sunlight and  
ultraviolet light for extended periods of time.  
Store lens filters away from dust and  
contamination.  
If temperatures appear to be reading low, ensure proper technique is  
being used (see page 11 to 12). Make sure the lens is clean and a new  
lens filter is attached.  
Thermometer  
• Use a soft, dry, clean cloth to clean the  
instrument display and exterior. Do not use  
abrasive cleaners of submerge in water or  
other liquids.  
If temperatures appear to be reading high, be sure a new lens filter is  
attached. Inspect the lens; if it is damaged, the thermometer must be  
serviced.  
• This instrument contains precision  
components and should not be subjected to  
extremes in temperature, humidity, direct  
sunlight, shock or dust.  
• Store unit in a location where the  
temperature remains fairly constant and  
within the range of 16°C to 40°C (61°F to  
104°F). To ensure that the Braun  
ThermoScan Thermometer is always ready  
to take a temperature (and avoid Err 4),  
store it in the room where it is most  
frequently used.  
To assure accuracy and sanitary practice, Braun recommends  
replacing the lens filter after each use. Should you run out of lens filters  
and need to take a temperature, you may use the following lens filter  
cleaning procedure: Clean the lens filter without removing it from the  
thermometer with a soft cloth or cotton swab moistened with alcohol or  
mild soap and water. Do not use hot or boiling water. Dry completely with  
a soft cloth before reusing. Replace lens filter as soon as possible with  
a new one (LF 40).
