PLEASE READ AND SAVE THESE INSTRUCTIONS
• This product is not intended to diagnose or treat any health problem or disease and should not be
used as a substitute for the consultation and advice of a physician or other medical professional.
• Thermometers should only be used under the supervision of an adult.
• This thermometer should be held during use; the patient should be seated or lying down during
readings.
• Before use, it is recommended that the patient avoid eating, drinking, smoking or exercising for at
least twenty minutes prior to taking a measurement. Never walk, run or talk during a measurement.
ABOUT BASAL BODY TEMPERATURE
Normal oral temperature readings vary throughout the day. Level of activity, time of day, beverages,
smoking and other factors may affect body temperature.
Basal body temperature is the lowest temperature reached during sleep. Basal temperature is measured
immediately after a full night's sleep, before moving, talking, drinking, getting out of bed, or any other
activity. It is best taken immediately upon awakening, but before reaching full consciousness – while
you are still half asleep. The reading should be taken at the same time each morning upon waking, and
you should note other factors that may alter your temperature, such as sleep disturbances, alcohol use,
illness, traveling, toothache, sunburn,medications, or the use of an electric blanket.
As basal temperature is charted over the course of weeks and months, patterns will be revealed that
can be used to determine when in your menstrual cycle ovulation occurs, which in turn indicates in
which days of your cycle that conception may occur. This pattern can help you to either achieve or avoid
pregnancy.
The typically acknowledged normal temperature of a healthy person is 98.60° F (37.00° C). In the
beginning of a menstrual cycle (which starts at the beginning of a period), the basal oral temperature
can range from 96.50° F to 98.00° F (35.80° C – 36.70° C). In the last two weeks of the menstrual
cycle, the basal temperature typically increases by about 0.50° F (0.30° C). The shift in basal body
temperature occurs at about the time of ovulation, during which conception occurs.
By charting basal body temperature throughout the menstrual cycle, a determination can be made as to
when ovulation is occurring, based on the increase in basal temperature. Ovulation occurs only once per
cycle, and intercourse at or near the time of ovulation may result in conception.
WARNINGS AND CAUTIONS
Please note that this thermometer is not intended for use as a contraceptive. Many factors may influence
body temperature; therefore, we can make no claims regarding the reliability of results in predicting ovula-
tion. Consult a healthcare professional for advice regarding contraception and family planning.
FAHRENHEIT CELSIUS SWITCHABLE FEATURE
This unit takes measurements in both Fahrenheit and Celsius. While the unit is OFF, press and hold the
POWER button. After the brief self-test, the unit will show the last reading in either °F or °C. Continue to
hold the POWER button, and display will change the mode and display the new temperature reading mode.
Release the POWER button and begin your reading.
MEMORY RECALL
This unit includes a recall of the last measurement taken. When the unit is OFF, press the
POWER button to turn the unit on, and release. After the self-test, the unit will briefly
show the last reading with an 'M' on the display.
OPERATING INSTRUCTIONS
Temperature should be taken immediately upon waking, at the same time each morning,
and before getting out of bed, moving, talking, drinking, or performing any other activity.
Ideally, the patient should still be half-asleep during the reading.
Press and release the POWER button to activate the thermometer. The unit will beep
and the display will show all of the digital display symbols as it performs a self-test before
showing the last reading in memory.
A Lo with a flashing °F will appear in the display, followed by a brief flash of the last reading in memory; the
display will return to the flashing Lo, indicating that the thermometer is ready for measurement.
ORAL USE
1.
Apply a probe cover if using; apply the probe cover before pressing the POW-
HEAT
HEAT
ER button.
POCKET
POCKET
2.
Place the probe under the tongue as near as possible to a heat pocket as noted
in the diagram. Readings will be progressively lower the further the probe is
from the indicated heat pockets.
3.
Hold the thermometer in place during the reading; do not bite down on the
thermometer. The mouth must remain closed to ensure accurate results. The reading should take
approximately 60-seconds.
4.
When the reading is complete and the peak temperature has been reached, the °F(°C) will cease
flashing.
5.
If the reading below 100.0°F(37.8°C), the unit will sound ten long beeps. If the reading is at or above
100.0°F(37.8°C), the unit will sound ten sets of three short beeps.
To turn the unit off, simply press the POWER button. The unit will automatically shut-off after
6.
approximately ten minutes.
7.
Record your readings to help track your ovulation.
PROBE COVER USE
Disposable, hygienic probe covers are recommended for use with stick thermometers to prevent contam-
ination. Probe covers are intended for one-time use only; a new probe cover should be used with each
application. Probe covers can commonly be found at your local retailer or can be ordered direct by using the
attached order form.
