English
The Braun ThermoScan thermometer has been carefully developed for accurate,
safe and fast human body temperature measurements in the ear. The shape of
the thermometer prevents it from being inserted too far into the ear canal to damage
the eardrum.
However, as with any thermometer, proper technique is critical to obtaining
accurate temperatures. Therefore, please read all instructions carefully and
thoroughly before using this product and keep the manual handy for future
reference.
Important
• The operating ambient temperature range for this thermometer is 50 °F to 104 °F
(10 °C to 40 °C).
• Do not expose the thermometer to temperature extremes below - 4 °F or over 122 °F
( - 20 / 50 °C) or excessive humidity ( > 95 % RH non-condensing).
• 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.
• If the thermometer is ever accidentally used without a lens filter attached, clean
the lens (see «Care and cleaning»).
• Always store thermometer in travel case, protective cover or plastic case.
• Basic safety precautions should always be observed, especially when using
the thermometer on or near children and disabled persons.
• Keep lens filters out of reach of children.
• This thermometer is intended for home use only.
• Use of this thermometer is not intended as a substitute for consultation with
your physician.
• Do not leave thermometer or lens filters with infants or children at any time.
How does Braun ThermoScan work?
The Braun ThermoScan thermometer measures the infrared heat
generated by the eardrum and surrounding tissue. To help ensure
accuracy, the thermometer «scans» by taking 8 measurements in
just one second and displaying the highest temperature.
The displayed ThermoScan temperature is the actual measured
ear canal temperature plus a mathematical adjustment to approximate
the familiar oral range. However, this is not necessarily the same as
an oral temperature measured at the same time.
Why measure in the ear?
The goal of thermometry is to measure core body temperature,
which is the temperature of the vital organs. Clinical studies have
shown that the ear is an excellent site to measure body temperature,
since ear temperatures reflect core body temperature. The eardrum
shares blood supply with the temperature control center in the brain,
the hypothalamus, allowing changes in body temperature to be
reflected sooner in the ear than at other sites.

• Axillary temperatures reflect skin temperature which may not indicate core body
temperature.
• Oral temperatures are influenced by drinking, eating and breathing through the
mouth.
• Rectal temperatures often 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 table1shows that ranges of normal also vary by site. Therefore, readings from different sites, even if taken at the
same time, should not be directly compared.
Axillary: 94.5 °F - 99.1 °F 34.7 °C - 37.3 °C
Oral: 95.9 °F - 99.5 °F 35.5 °C - 37.5 °C
Rectal: 97.9 °F - 100.4 °F 36.6 °C - 38.0 °C
ThermoScan2: 96.4 °F - 100.4 °F 35.8 °C - 38.0 °C
• Also, a person’s normal temperature range tends to decrease with age. The following table shows normal ThermoScan ranges by age.
Normal ThermoScan temperature ranges
2
0 - 2 years 97.5 °F - 100.4 °F 36.4°C - 38.0 °C
3 - 10 years 97.0 °F - 100.0 °F 36.1°C - 37.8 °C
11 - 65 years 96.6 °F - 99.7 °F 35.9°C - 37.6 °C
> 65 years 96.4 °F - 99.5 °F 35.8°C - 37.5 °C
• However, the range of normal also varies from person to person and fluctuates
throughout the day. It is therefore important to determine your and your family
members’ normal temperature ranges. 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.
