authorization.
To avoid inaccurate measurements ALWAYS use this thermometer
with a new, clean, disposable lens lter.
If the thermometer is accidentally used without a disposable lens
lter, clean the lens after use (see“Care and cleaning”).
Keep disposable lens lters 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.
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 a temperature elevation occurs on persons
that are:
• Neonates and infants under 3 months (Consult your physician
immediately if the temperature exceeds 99.4 °F [37.4 °C])
• Individuals over 60 years of age (Fever may be blunted or
absent in older individuals)
• Individuals having diabetes mellitus or a weakened immune
system (e.g., HIV positive, cancer chemotherapy, chronic
immunosuppressant treatment, splenectomy)
• Individuals who are bedridden (e.g., nursing home patient,
stroke, chronic illness, paraplegia, quadriplegia,
surgical recovery)
• A transplant recipient (e.g., liver, heart, lung, kidney)

5
This thermometer is not intended for pre-term babies or
small-for-gestational age newborn babies (birth to 4 weeks of age).
Pre-term is dened as babies born before 37 weeks of gestation.
Small-for-gestational-age is dened as a newborn baby, born at 37
weeks or later, with a weight below the 10th percentile for
newborn babies of the same gestational age.
This thermometer is not intended to interpret hypothermic
temperatures. If the device displays a temperature of 97.5°F
(36.4°C) or less with an LED backlight color of green or white, and
the individual is exhibiting atypical symptoms or behaviors,
contact your physician or health care professional.
DO NOT allow children to take their temperatures unattended.
Please consult your physician if you see symptoms such as
unexplained irritability, vomiting, diarrhea, dehydration, changes
in appetite or activity, seizure, muscle pain, shivering, sti neck,
pain when urinating, etc., even in the absence of fever.
Even in the absence of fever, those who exhibit a normal
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.

Color-coded fever guidance
Color-coded fever guidance helps you to better understand the
meaning of your child’s temperature with the color indicated on
the display.The color-coded screen displays GREEN for a normal
temperature,YELLOW for a fever, and RED for a high fever.
Color range Reading Meaning
Green >96.3 °F - 99.4 °F
(>35.7 °C - 37.4 °C) Normal
Yellow >99.4 °F - 101.3 °F
(>37.4 °C - 38.5 °C) Fever
Red >101.3 °F
(>38.5 °C ) High Fever
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 uctuates throughout the day. Therefore, it is
important to determine normal temperature ranges.
How to use your Braun ThermoScan®
Before taking the temperature, make sure the ear is free from
obstructions or excess earwax.
DO NOT attempt to take the reading without a hygienic lens lter
on – the measuring sensor must be kept protected and clean from
earwax to give accurate readings.
Change the hygienic lens lter with each use to ensure hygiene,
to keep child safe from cross-contamination and to ensure earwax
residues on the hygienic lens lter do not impact accuracy of
the reading.

1. To turn the thermometer on, push the“start”button (4)
as shown on page 3.
During an internal self-check, the display
shows all segments.
The reading shown on the screen is the last
temperature taken.
Flashing symbol of lens lter will appear if no
lens lter is attached.Temperature can be
taken only if lens lter is mounted on
the probe.
The thermometer is ready to use after
two beeps and the non-ashing ear
icon appears.
2. Fit the probe (3) snugly into the ear canal,
then push the “start” button (4).
One beep signals normal temperature. Audio
temperature indicator will trigger 2
consecutive beeps when the reading is equal
or higher to 99.5 °F (37.5 °C) and 4 beeps if the
reading is equal or higher to 101.4 °F (38.6 °C).
The result is shown on the display (7).
3. Gently pull o the hygienic lens lter (2).
Do not use force in removing the hygienic
lens lter.
4. Put on a new, clean, hygienic lens lter by
snapping into position.
5. Place the protective cap on (1).
The BraunThermoScan® 4 Ear thermometer turns
o automatically after 60 seconds of inactivity.
The thermometer can be turned o by pressing
and holding the start button for more than
5 seconds.

Hygienic lens filters (LF40/LF20)
Use a clean hygienic lens lter with each measurement:
1. To ensure hygienic use
2. To protect your child from cross-contamination
3. To ensure earwax residues do not impact accuracy
of the reading
Earwax and dirt on the tip of the hygienic lens lter, even a
microscopic layer, can create an obstacle between the sensor and
the infrared heat emitted by the ear and impact the accuracy
of the measurement.
Temperature taking hints
• Replace the hygienic lens lter with every use to maintain
hygiene and accuracy.
• A measurement taken in the right ear may dier 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 inuence 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
– been recently swimming or bathing, or
– been wearing hearing aids or headphones for an extended
period of time
In these cases, remove the individual from the situation and wait
20 minutes prior to taking a temperature.

9
• If ear drops or other ear medications have been placed in the
ear canal of one ear, take the temperature in the untreated ear.
• Nursing mothers should not take a temperature measurement
on themselves or have their temperature measured by another
individual while or immediately after nursing a baby, as nursing
can aect body temperature.
Care and cleaning
The probe tip (5) is the most delicate part of the thermometer. It
has to be clean and intact to ensure accurate readings.
If the thermometer is accidentally used without a hygienic lens
lter, clean the probe tip as follows:
Very gently wipe the surface with a cotton swab
or soft cloth moistened with alcohol.
DO NOT use cleaners other than alcohol on
the probe tip. Use of other cleaners could
damage the tip.
Once the alcohol has dried completely, a new hygienic lens lter
can be put on and a temperature measurement taken. If the probe
tip is damaged, please contact Consumer Relations.
Use a soft, dry cloth to clean the thermometer display and product
exterior. DO NOT use abrasive cleaners. NEVER submerge this
thermometer in water or any other liquid.
Store the thermometer and hygienic lens lters in a dry location
free from dust and contamination and away from direct sunlight.
Additional hygienic lens lters (LF40 /LF20) are available at most
stores selling the BraunThermoScan® 4 Ear thermometer.
