Congratulations on your purchase of this product.
Please read the instructions carefully before using
the thermometer for the rst time and keep these
instructions in a safe place. This product is intended for
the measurement of human body temperature.
Basal body temperature (BBT)
Your basal body temperature (BBT) is your lowest
body temperature in a 24-hour period. This Basal
Thermometer is sensitive enough to help you keep
track of minute changes in your body temperature. For
BBT-charting you take your temperature rst thing in
the morning, preferably while you are still in bed. You
can record your basal temperature on the BBT-chart
that you can nd on www.iProven.com/bbt-chart
Operating Instructions
1. Before use please disinfect the probe.
2. Press the button once to switch on the device.
3. The thermometer runs a check during which all the
digital segments will appear on the LCD and a soft
beep will sound.
4. After this check the LCD shows --.-- ˚F (or˚C), the
thermometer is now ready for use.
5. Place the thermometer in the desired measurement
position (oral or rectal).
6. Wait until the measurement is taken and saved in
the memory. This is indicated by 3 soft beeps.
7. Write the result in the chart directly or use the
memory function later.
8. Press the button to switch o the thermometer.
If the thermometer is not switched o, it will
automatically switch o after 3 minutes.
Memory function
To see the saved measurement:
1. Make sure the thermometer is o. If needed, press
the button once to switch o.
2. Hold the button for 4 seconds and release it as soon
as “LAST” appears in the LCD.
3. The last measurement will now be shown.
4. The thermometer will automatically switch o after
3 minutes.
Switching ˚F and ˚C
To switch to the other scale:
1. Make sure the thermometer is o. If needed press
the button once to shut o.
2. Hold the button for 7 seconds (ignore “LAST” and
keep holding) release the button as soon as “SET”
appears.

3. “C-F” will appear and the current setting is ashing.
4. Press the button to change.
5. Leave the button untouched for 3 seconds, the
thermometer will save the setting and switch o.
Methods of measuring temperature
The accuracy of a body temperature reading
depends on the position where it is measured. When
charting the body temperature, always indicate the
measurement position. The usual measuring time is
approximately 40 to 60 seconds. A measurement is
only completed when the temperature rises less than
0.05˚F(0.1ºC) within 16 seconds.
NOTE: the axillary measurement is NOT valid for Basal
Body Temperature measuring.
Rectal Measurement
From a medical point of view this is the most accurate
method because this position is closest to the core of
the body. The thermometer tip is inserted carefully
into the rectum for a maximum of 1“ (2 cm).
Oral Measurement
This is the most convenient measurement position
for daily BBT measurements. There are dierent
heat zones in the mouth. As a general rule, the oral
temperature is 0.5-1.4˚F (0.3-0.8 ˚C) lower than the
rectal temperature. To ensure that the reading is as
accurate as possible: place the thermometer tip to
the left or right of the root of the tongue. Keep the
thermometer tip constantly in contact with the tissue
under the tongue. Keep your mouth closed during the
reading.
Important! Eating, drinking and breathing through
the mouth will inuence the temperature of the
mouth tissue. You will not be able to get an accurate
BBT reading after eating or drinking. Also try not to
breathe through the mouth within 3 minutes before
taking an oral measurement.
Cleaning and disinfection
The best way to clean the thermometer tip is by
applying a disinfectant (e.g. 70% ethyl alcohol) with
a damp cloth. This waterproof thermometer can be
immersed in liquid or lukewarm water for thorough
cleaning and disinfection.
Safety precautions
• Do not expose the thermometer to water hotter
than 122˚F (50˚C).
• Do not expose the thermometer to high
temperatures or direct sunlight.
• Do not drop the thermometer. It is not shock-proof
nor impact-resistant.
• Do not bend or open the device (except the
battery compartment).
• Do not clean with thinners, petrol or benzine; Only
clean the thermometer with water or disinfectant.
• Do not immerse the thermometer under water
deeper than 15cm for longer than 30 minutes.
• The thermometer contains small parts (including a
battery) which can be swallowed by children. For this
reason, do not leave the thermometer unattended in
the hands of children.
• If the ambient temperature is over 95ºF(35ºC), dip
the thermometer tip in cold water for 10 seconds prior
to measuring the temperature.
• Persistent fever, in particular in children, has to be
treated by a doctor. If this occurs please get in touch
with your doctor!
