III. HOW TO TAKE ACCURATE BASAL TEMPERATURES
To obtain an accurate basal temperature, you must take your temperature when you first awake
in the morning. For best results, this waking temperature should be taken at the same time each
morning. Since any activity may tend to raise your temperature, do not get out of bed until you
have taken your basal temperature. Postpone going to the bathroom, eating, smoking or drinking
until after taking your temperature. Cold drinks lower mouth temperature; hot drinks, smoking and
exercise cause higher readings. Using an electric blanket or heating pad can affect your basal
temperature. If you use one, it should be kept at the same setting each night throughout the time
you are taking your basal temperature.
SHOULD I USE THE ORAL, VAGINAL OR RECTAL METHOD?
Since temperatures taken at different sites can vary, it is important to select one method and then
take your temperature the same way every day. You must use either the oral, vaginal or rectal
method. Using more than one method will provide inaccurate results.
IV. TAKING YOUR BASAL TEMPERATURE
Select oral, vaginal or rectal as your measurement based on professional
recommendation.
TURNING ON THE THERMOMETER
To turn on the thermometer, push the multi-function
button at the tip of the unit. A short "beep" tone
signals the thermometer is ON. A display test is
performed. Figure 1 indicates what appears on
the display.
The thermometer will then display the last
temperature taken.
Then, at an ambient temperature of less than 32°C
an "L" and a flashing "°C" appears on the display.
The thermometer is now ready for use.
FUNCTION TEST
Proper functioning of the thermometer is
tested automatically each time it is turned on.
If a malfunction is detected (measurement
inaccuracy), this is indicated by "ERR" on the display, and a measurement becomes impossible.
In this case, start the procedure again. If the problem persists the thermometer must be replaced.
USING THE THERMOMETER
During a measurement, the current temperature is displayed continuously. The "°C" symbol flashes
during this period of time. If the signaling tone sounds (beep, beep, beep, beep 10 times) and the
"°C" is no longer flashing, this means that the measured increase in temperature is now less than
0.1°C in 8 seconds and that the thermometer is ready for reading.
To prolong the life of the battery, turn it off after use by pressing the multi-function button.
Otherwise, the thermometer will automatically turn off after about 9 minutes.
STORAGE OF MEASURED VALUES
When turning the thermometer on, the maximum temperature stored automatically at the last
measurement will be displayed. At the same time, a small "M" for memory will appear at the right of
the display. After 3 seconds, this value will disappear and the thermometer will switch to the normal
measurement mode. The stored value is erased.
