4. Introduction
The temperature measurement varies depending on the part of the body where the
measurement is taken. In a healthy person, the variance can be between 0.2°C and 1°C
(0.4°F and 1.8°F) in dierent parts of the body.
The result of FT90 is shown as oral temperature.

11
Normal temperature range with various thermometers
Measurements Thermometer used
Forehead temperature 35.8 °C to 37.6 °C
(96.4 °F to 99.7 °F) Forehead thermometer
Ear temperature 36.0 °C to 37.8 °C
(96.8 °F to 100.0 °F) Ear thermometer
Oral temperature 36.0 °C to 37.4 °C
(96.8 °F to 99.3 °F) Conventional thermometer
Rectal temperature 36.3 °C to 37.8 °C
(97.3 °F to 100.0 °F) Conventional thermometer
Note:
• Temperatures measured with dierent thermometers should never be compared with one
another.
• Tell your doctor what type of thermometer you used to take your temperature and on what
part of the body. Also bear this in mind while you are monitoring yourself.
Holding the thermometer for too long in the hand before taking a measurement can
cause the device to warm up. This means the measurement could be incorrect.
Influences On Body Temperature
• A person’s individual metabolism
• Age
Body temperature is higher in babies and toddlers than in adults. Greater temperature
fluctuations occur faster and more often in children. Normal body temperature decreases
with age.
• Clothing

12
• Outside temperature
• Time of day
Body temperature is lower in the morning and increases throughout the day towards
evening.
• Activities
Physical and, to a lesser extent, mental activities increase body temperature.
Note:
Taking the body temperature provides a current measurement of a person’s temperature.
If you are uncertain about interpreting the results or if the values are abnormal (e.g. fever),
please consult your doctor. This also applies in the case of slight temperature changes if
there are other symptoms of illness such as agitation, severe sweating, flushed skin, fast
pulse rate, tendency to collapse, etc.
5. Initial Use
If provided, pull out the battery insulating strip at the battery compartment or remove the
protective film from the battery and insert the battery with the correct polarity.
6. Switching On and Setting The Thermometer
The measuring sensor should be cleaned before and after each use, to eliminate dirt
and fingerprints and ensure accuracy of your readings.
Briefly press the On/O button .
After a brief self-test and two short beeps the thermometer is ready for forehead
measurement.
The device always starts up in forehead temperature mode .

7. Forehead Measurement
Briefly press the On/O button .
After a brief self-test and two short beeps the device is ready for forehead temperature
measurement. The device is in forehead temperature mode. This is indicated by the
symbol.
Note:
Remember that
• physical activity, increased perspiration on the forehead, taking vasoconstrictive
medication and skin irritations can distort the result.
• the forehead must be free from perspiration and cosmetics.
• before taking a reading, please remain indoors at room temperature for 5 minutes avoiding
exercise or taking a bath for 30 min prior reading.
• in case of doubt, please measure several times and take the highest measurement value.

16
Hold the thermometer 2 – 3 cm (0.78 – 1.18 in) from the indicated point.
Press the Start-measurement button and move the thermometer from
side to side over the forehead area (Fig. 8). During measurement you will
hear short beeps (only if the acoustic signal is activated), which signal
that the thermometer has found a new highest measurement. End of
measurement is signaled by a long beep.
Release the Start-measurement button. You can now read the
measurement value.
Note:
Only one single measurement is taken at a single spot in the middle of the forehead.
The display also shows the symbols or depending on the measurement:
Symbol indicates that the body temperature is equal to or higher than 38°C,
whereas symbol indicates a measured value below 38°C (100.4°F).
If the acoustic signal is switched on, three beeps will sound once the measurement is
complete if the temperature is equal to or higher than 38°C (100.4°F).
The device is ready to take another measurement when two short beeps sound and the
forehead symbol stops flashing.
The measurement is automatically saved with the date/time and classification / .
Note:
Holding the thermometer in one place too long may cause a higher ambient temperature
reading which could make the body temperature reading lower than usual.
7.1 Displaying Saved Measurements
The device only stores measurements in forehead temperature mode . The device
automatically stores the values from the last 60 measurements.
When 60 storage places are exceeded the oldest value is deleted.
Fig. 8

17
The memory can be called up as follows:
• With the thermometer switched on, press and hold the MODE/MEM button for 5 seconds.
The most recent measurement is displayed.
• With each subsequent pressing of the MODE/MEM button, first the storage space number
is displayed followed by the measurement upon release.
• In the upper line, the time and date are displayed alternately.
8. Measuring Object Temperature/Room Temperature
Object temperature mode
If you want to measure an object temperature with this thermometer, switch
to object temperature mode.
• With the thermometer switched on, briefly press the MODE/MEM button.
The device switches to the object temperature mode .
