Infrared Forehead Thermometer DT-8807S
• The minimum measurement time until the beep must be
maintained without exception.
• Discuss the measured values with your doctor.
• The temperature measured at the forehead area differs
from the core body temperature, which is obtained by
taking an oral or rectal measurement with a clinical ther-
mometer.
• Check the measurement result with a conventional clini-
cal thermometerr:
1. if you are using the thermometer for the first time, or
you are not yet familiar with the correct use of the
device
2. if the measurement result is surprisingly low and
does not match the state of health
3. for newborns up to 6 months of age
4. for persons, especially small children, who react
unusually in the presence of fever.
Caution!
Risk of injury:
• The instrument contains small parts that could be acci-
dentally swallowed by children. Keep this instrument
and the batteries out of reach of children. Use under
parental supervision.
• Batteries contain harmful acids and may be hazardous if
swallowed. If you suspect a battery could have been
swallowed or otherwise caught in the body, seek med-
ical help immediately.
• Batteries must not be thrown into a fire, short-circuited,
taken apart or recharged. Risk of explosion!
• Low batteries should be changed as soon as possible to
prevent damage caused by leaking. Never use a combi-
nation of old and new batteries together, nor batteries of
different types.
• Wear chemical-resistant protective gloves and safety
glasses when handling leaking batteries.
Important information on product safety!
• Do not place the device near extreme temperatures,
vibrations or shocks.
• Protect the device from large or abrupt ambient temper-
ature changes.

• Steam, dust, smoke, etc., can prevent accurate mea-
surement by obstructing the device's optics.
• The device is not waterproof. Protect it from moisture.
Do not immerse in water or other liquids.
• To clean and disinfect the unit, please follow the instruc-
tions in the section "Care and Maintenance".
4. Measuring procedure
• Every object releases infrared energy. The optical detec-
tor senses the infrared energy, converts this information
into a digital reading and the surface temperature is dis-
played.
4.1 Measurement of body temperature
• In the default setting, in body temperature mode, the
thermometer measures the temperature of the infrared
heat given by the arterial blood supply under the fore-
head area and converts this temperature into an oral
equivalent temperature. The measurement result is dis-
played within 1 second. The contactless measuring
method allows, for example, to take the temperature of
babies without disturbing them during sleep.
• Many people believe that normal body temperature is
37°C, however body temperature, like blood pressure,
varies from person to person and during the day. It may
range from 35.5°C (95.9°F) to 37.8°C (100.4°F).
• We should remember as well that oral temperature is
normally lower by 0.5°C (0.9°F) from rectal tempera-
ture. The forehead temperature is converted by the
infrared forehead thermometer to the commonly used
oral temperature. For some people it may show some
difference from their normal oral temperature.
Therefore: Practice is important!
• We recommend that you practise using the thermome-
ter on yourself and your family when you're in a healthy
condition. In this way you can improve your technique
and obtain a reference value for normal body tempera-
ture of each member of your family. This in turn will
help you to feel more confident to take the temperature
when someone is ill.
