place.
Your new forehead thermometer detects body temperature in an ab-
solutely precise and painless way.
solutely precise and painless way.
It is ideal to carry out measurements on babies, even while they are
sleeping.
The new infrared measurement technology offers a greater reliability
and above all a longer life of the instrument.
It is equipped with a wide LCD display for an easy reading.
It has also an acoustic signal for completed measurement of the body
temperature and of automatic switching-off after one minute of inac-
tivity, which allows to extend the duration of the batteries.
It is really easy to be used and allows the measurement of body and
room temperature.
It measures temperature in Celsius (C°) and Fahrenheit (F°) degrees.
It stores in memory the last 25 measurements performed to evaluate
eventual variations.
NB: the temperature shown on the display is equal to
the oral temperature, i.e. temperature measured on the
forehead is translated as if it were measured in the mouth.

GENERAL WARNINGS
1. Self-measuring means control, it does not mean
diagnosis or treatment.
Any unusual levels should always be discussed with
your doctor.
Under no circumstances must you change the dose of
medicines prescribed by your Doctor.
2. The forehead thermometer is a very sensitive
instrument.
EnglishINFRARED FOREHEAD THERMOMETER
Please handle it with care and avoid knocks.
Do not press, bend, drop or break the thermometer
into small pieces.
3. Keep it out of the reach of children.
4. The thermometer must not be exposed to extreme
temperatures, direct sunlight or sources of heat.
It must be kept in a cool, dry and clean place.
5. Do not touch the probe with your fingers.
Do not dismantle the thermometer.
6. Do not immerse the thermometer in water or other
liquids.
7. The forehead thermometer must not be used for
rectal, oral or armpit temperature reading.
8. The precision of the measurement can be jeopard-
ized by: great perspiration of the forehead, use of
vasoconstrictive drugs and skin irritations.
9. Clean the temple where the probe will lean before
performing the measurement.
10. Measure the temperature far from direct sunlight
and wind.
11. This thermometer has to be used to measure
temperature on forehead (with skin contact) as shown
on the cover page.
A HIGH TEMPERATURE
A high temperature should be considered a symptom and not an ill-
ness. Usually it is the sign that our organism is fighting against an
infection.
In fact, it represents a defensive reaction of our organism that is char-
acterised by an increase in body temperature above 37°C and by an
increase in heartbeat and breathing frequency.
The normal temperature inside our organism is around 37.5°C, which
is the value read with the rectal method, the temperature in the
mouth is lower by about 0.5°C (37°C), while that under the armpit
is lower by 1°C (36.5°C).
WF-2000Instructions and warranty
Therefore it is very important that the temperature is correctly meas-
ured using the most effective method, and preferably not in those
moments when body temperature could be higher (on waking, after
meals).
The temperature of a healthy person is also affected by the following
factors:
• The person’s individual level (individual metabolism).
• Age (body temperature is higher in babies and small children
and falls with increasing age. Greater temperature fluctuations
occur in children faster and more often.).
• Clothing.
• The outside temperature.
• The time of day (Body temperature is lower in the morning
and rises as the day goes on).
• Preceding physical activity.
• Measuring method.
• Phase of the menstrual cycle.
You should remember that skin temperature is easily affected
by the room temperature; in fact, taking the temperature under the
armpit is much less reliable with respect to oral and rectal
readings.
However, the temperature that is read on the forehead is extremely
reliable and close to the real body temperature, as just a few mm from
the skin on the forehead the temporal artery passes which carries the
blood to the brain.
This means that your new infrared forehead thermometer measures
the temperature of the blood in the artery that passes underneath
the skin. This is a highly appreciated method as it is very simple,
precise and reliable.
The graph below shows a list of the average “normal” temperatures.
Please remember, that the thermometer must be in the
room where the temperatures is to be taken at least half an
hour beforehand, while the person must be present at least
10 minutes beforehand.
However, we recommend that you learn to recognise your
EnglishINFRARED FOREHEAD THERMOMETER
normal body temperature when you are well, to correctly
interpret the different readings.
MEASURING METHOD NORMAL AVERAGE
ARMPIT 36.5°C
ORAL 37°C
RECTAL 37.5°C
EAR 37°C
These different thermometers are suitable for measuring the temper-
ature in different parts of the body: forehead thermometer: measure-
ment only on the forehead, ear thermometer: measurement only in
the ear, rod thermometer: rectal (conventionally in the back passage),
axillary (under the arm) or buccal measurement (inside the cheek)
and under the tongue (sublingual).
The temperature varies depending on the part of the body where it is
measured. The variation can be between 0.2 – 1° C.
Temperatures measured with different thermometers cannot be com-
pared with one another. Tell your doctor or take into account when
diagnosing yourself what thermometer you used in what part of the
body to measure the temperature.
INSERTING/REPLACING THE BATTERY
The battery has to be urgently replaced when on the display the sym-
bol of “discharged battery” appears.
Before replacing the battery, switch off the thermometer to avoid
damaging the mechanism.
1) extract the screw from the cover of the battery compartment.
2) open the cover and remove the battery
3) insert the new battery and place the positive pole upwards.
4) place the cover back on the battery compartment.
5) screw the screw in the cover.
Do not dispose used batteries as domestic waste, but deposit them
in the proper collection points.

Lean the probe on the right or left temple;
press the key
SCAN and keep it pressed, then slowly move the probe around
the temple.
The thermometer emits beeps indicating that the measurement
is taking place.
5) A longer and more intense acoustic signal indicates that
the measurement has ended (Time necessary to perform the
measurement ranges from 5 to 30 second according to the
temperature of the person).
Should the temperature exceed 37.5°C, the thermometer emits
a long beep followed by other three shorter beeps.
6) Release the key SCAN and then detach the probe from the
temple; read the measured value on the display
NB:
the temperature shown on the display is equal to the oral
temperature, i.e. temperature measured on the forehead is
translated as if it were measured in the mouth.
7) The device switches off automatically after 1 minute, if it is
not used.
MEASUREMENT OF THE ROOM TEMPERATURE (

If the SCAN key is kept pressed, temperature is updated
continuously.
4) The device switches off automatically after 1 minute, if it is
not used. When it is switched on again, the display shows the
forehead temperature measurement function (HEAD).
CELSIUS/FAHRENHEIT
This thermometer can measure temperature both in Celsius and
Fahrenheit degrees.
Each time you wish to change the measurement unit, proceed as
follows:
1) With switched off thermometer, keep the key SCAN pressed
without releasing it for some seconds, and then press
contemporaneously the key ON/MEM until the displays shows
°F (or °C).
2) The thermometer emits two beeps; at this point, release the
key SCAN and the key ON/MEM.
Now the measurement unit has been changed.
Proceed with the measurement according to paragraph
“INSTRUCTIONS FOR A CORRECT USE”.
MEMORY FUNCTION
This device stores in memory the last 25 measurements performed
to evaluate eventual variations. The measurements are stored auto-
matically after that the thermometer has switched off.
Only forehead temperatures (HEAD) included between 22°C and
42.2°C (71.6°F and 108.0 °F) are stored.
After the first 25 measurements, the oldest data are erased automati-
cally.
To call up saved measurements, switch on the thermometer, and
press the key ON/MEM (Every time the key is pressed, saved data are
scrolled). On the upper part of the display appears the symbol “M”
and before each stored data appears the corresponding number (1=
most recent measurement - 25 oldest measurement).
The stored measurements are displayed for about 1 minute.
After about 1 minute from releasing the ON/MEM key, the device
switches off automatically.
CLEANING AND MAINTENANCE
Before and/or after each use, clean the probe of the thermometer
with a soft cotton cloth moistened with water or alcohol to assure
accurate measurements and to avoid microbial contaminations. The
probe is the most delicate part of the thermometer; pay utmost care
during the cleaning.
Let the probe dry completely for about 30 minutes.
The thermometer body has to be cleaned with a soft and dry cloth.
THE BODY OF THE THERMOMETER HAS NOT TO BE WASHED WITH
WATER.
Absolutely neither use abrasive products, nor plunge the thermom-
eter in water or other liquids.
Store the thermometer in a dry and clean place away from direct
sunlight.
