VI. 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 tem-
perature. Postpone going to the bathroom, eating, smoking or drinking until after taking your basal tem-
perature. 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 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 everyday. You must use either the oral or rectal method. Using more than one
method will provide inaccurate results, consult a professional if you are unsure which is best for you.
VII. TAKING YOUR BASAL TEMPERATURE
Select oral or rectal as your measurement based on professional recommendation.
Press the On/Off button to activate the thermometer. The digital display will show the following:

This ensures all parts of the
LCD are functioning properly.
ORAL METHOD
Do not drink hot or cold fluids, exercise, smoke, or perform other activities that will raise or lower tem-
perature readings when compared to your normal, average temperature. The mouth should remain closed
up to 5 minutes before attempting a reading.
1. Cover the thermometer's tip with a probe cover.
2. Place the sensor tip well under the tongue as indicated by the " "
(see Figure 2).
3. When the peak temperature is reached (usually within 60 seconds), a beep signal
will sound and the "°F" sign will stop flashing. The temperature is now ready to read
and will not change when the thermometer is removed.
4. Turn the thermometer off by pressing the On/Off button. If you forget to turn it off,
the thermometer will automatically turn off after approximately 10 minutes.
5. Dispose of used probe cover.
RECTAL METHOD
Once used rectally, the thermometer should not be used orally for sanitary reasons.
1. Put a cover on probe tip and lubricate with a water-soluble jelly for easier insertion. Do not use a
petroleum jelly. Read the label of the lubricant to be sure you are using the right kind.
2. Gently insert the tip of the thermometer NO MORE THAN 1/2 inch into the rectum. If you detect resist-
ance, stop.
3. When the peak temperature is reached (usually within 60 seconds), a beep signal will sound and the
"°F" sign will stop flashing. The temperature is now ready to read and will not change when the ther-
mometer is removed. Remember that the rectal method produces a temperature 1°F higher than a
temperature taken orally.
4. Turn the thermometer off by pressing the On/Off button. If you forget to turn it off, the thermometer will
automatically turn off after approximately 10 minutes.
5. Dispose of used probe cover.

VIII. TEMPERATURE RANGES (ORAL) BEFORE AND AFTER OVULATION
Your basal temperature before ovulation is usually in the range of 96.5°F to 98°F, (35.8°C to 36.7°C).
The most frequent range is between 97.4°F to 97.7°F (36.3°C to 36.5°C). After ovulation the basal tem-
perature rises about 0.5°F (0.3°C) and stays in that higher range until the beginning of the next men-
strual period. The highest probability of conception is during the days immediately prior to ovulation as
well as on the day of ovulation itself.

IX. OTHER IMPORTANT INFORMATION
Remember that the thermometer is designed only to help determine when ovulation has occurred.
Mucus observations, as noted in Section V, " THE FEMALE REPRODUCTIVE CYCLE", can also be help-

ful when recorded as shown on the sample chart. Notation of these changes, in addition to your tem-
perature pattern, will assist your physician or counselor in providing you with proper guidance.
It is commonly suggested that couples who have had difficulty in achieving pregnancy should not have
intercourse more than once a day nor on consecutive days, in order to maintain satisfactory quantities
of sperm. The most fertile time continues up through the first day of drying up of the mucus or the first
day of temperature elevation, whichever comes later.
The temperature record should be maintained on a daily basis. If pregnancy is achieved, the basal tem-
perature will remain elevated for several months. A temperature pattern that remains elevated for 21 days
(a week or more than the usual elevated pattern) is a good indicator that pregnancy has been achieved.
If you do not become pregnant after six months, see your doctor. If you believe you are pregnant,
Figure 1
see your doctor immediately.
X. CARING FOR YOUR BASAL THERMOMETER
Do not soak the display area in water. Only the probe is waterproof. Do not clean the probe with boiling
water. After use, clean the thermometer by wiping it with soap and water or rubbing alcohol (70% iso-
propyl alcohol). To prevent damage and contamination, store the unit in its protective case after each
Figure 2
use. Do not store the unit in direct sunlight. Keep the thermometer in a dry, cool area and out of the
reach of children. Do not attempt to disassemble the unit except to replace the battery.
CHANGING THE BATTERY
The battery provided with your thermometer will last for approximately 200 hours of normal use. When
the «
» flashes in the display's right, bottom corner, the battery needs to be replaced. Make sure a
battery of the same type is on hand and proceed as follows: Pull off the battery compartment lid. Use a
small "Phillips" screwdriver to remove the battery holder. Insert new equivalent battery type (1.55v, LR41
or SR41). Ensure battery is correctly positioned with the "+" facing up or towards the back of the unit.
Carefully screw back into place and replace the battery compartment lid. Properly dispose of the old bat-
tery according to local regualtions. Your OviTrack
KEEP BATTERY OUT OF REACH OF CHILDREN. SWALLOWING BATTERY COULD BE HARMFUL.
BATTERY SHOULD NOT BE CHARGED OR PLACED INTO EXTREME HEAT AS IT MAY EXPLODE.
