VI. CARING FOR YOUR Ovulation Digital Thermometer
Wash the tip of the thermometer with warm (not hot) soapy water before and after each use. Or,
wipe the area with isopropyl alcohol before and after each use.
CHANGING THE BATTERY
When the " " appears in the lower right of the display, the battery
is exhausted and needs replacing. Make sure a battery of the
same type is on hand and proceed as follows: Remove battery
compartment lid. Remove battery. Insert new equivalent battery
type (1.5/1.55v, 392 SR41W). Ensure battery is correctly positioned
with the "+" facing up or towards the back of the unit. Carefully
replace the battery compartment lid. Ensure "O" ring (washer) is
in place to maintain water resistance. Properly dispose of the
batteries according to local regulations, keeping them from small
children and heat.
WARNING
KEEP BATTERY OUT OF CHILD’S REACH. SWALLOWING BATTERY COULD BE HARMFUL.
BATTERY SHOULD NOT BE CHARGED OR PLACED INTO EXTREME
HEAT AS IT MAY EXPLODE.
VII. IMPORTANT INFORMATION TO HELP YOU UNDERSTAND
THE BASAL TEMPERATURE METHOD
Hormonal changes associated with ovulation produce a slight rise in a woman’s basal body
temperature, (approximately 0.3°C/0.5°F), as well as other recognizable signs such as changes in
cervical mucus. Learning to record and interpret basal temperature changes is known as the "Basal
Temperature Method." By monitoring the basal temperature changes, couples, in conjunction with
their physician or family planning counselor, may be able to determine when ovulation takes place.
Monitoring other symptoms, such as cervical mucus changes, can assist in determining the fertile
days prior to ovulation. When temperature changes are used in conjunction with other fertility
symptoms, such as the cervical mucus, this is known as the "Sympto-Thermal Method."
Determination of ovulation can be used to time sexual intercourse during fertile days to aid in the
likelihood of achieving pregnancy. The basal temperature change used in conjunction with other
methods, can also be used to help determine times for avoidance of sexual intercourse to avoid
pregnancy.
Please note, use of Basal Temperature Method only may not be effective in avoiding pregnancy.
VIII. THE FEMALE REPRODUCTIVE CYCLE
In order to understand the Basal Temperature Method it is helpful to review the basics of human
female reproductive activity.
A. THE ROLE HORMONES PLAY IN OVULATION
At the beginning of each menstrual cycle, the pituitary gland secretes a hormone FSH or Follicle
Stimulating Hormone, that acts upon the ovaries to prepare for ovulation. As one or more follicles
in an ovary prepare for ovulation, they secrete another hormone called estrogen, that prepares the
uterus for pregnancy by causing the inner lining of the uterus to thicken.
