TROUBLESHOOTING1. Wide differences in readings

2. Nothing appears in the display section when the power switch is pressed.

TAKING THE TEMPERATUREIf possible, a full probe cover covering all sections should be used. Replace the probe coverwith a new one after each use.Probe covers are included with the thermometer, place a probe cover carefully over the tip.

1. Press the ON/OFF button.NOTE:When a temperature other than 37°C(98.6°F) isdisplayed, please refer to the “TROUBLESHOOTING”section for details to correct the problem.

2. Apply the thermometer to the measurement site.Use the oral or underarm site for measurement.

NOTE:Even if the “L” indicator fails to display (when only the temperature is displayed), thisis not an error. So the temperature may be taken as is.

3. When the reading is ready, the thermometer will emit a [beep-beep-beep] sound three times. Remove the thermometer from themeasurement site and read the result.

BUZZER NOTIFICATION TIMING

NOTES:• The buzzer notification timing is based on an environmental temperature of 23

degrees without the probe cover.• There will be individual differences in the measurement results.

4. Turn o� the thermometer and return it to its protective case.NOTES:• The reading will automatically be stored in memory.• Although the thermometer will automatically switch itself off 30 minutes after use or

after 3 minutes when it has not been used; it should be turned off manually toconserve the battery.

BASAL BODY TEMPERATURE (BBT) CHART

WHEN PREGNANCY IS DESIREDThe life of the egg released during ovulation is about 24 hours and the sperm is capable offertilization for approximately 3 days so the period when pregnancy is most likely to occur isin the 5-day period from 3 days prior to the day of ovulation through the day after ovulation.

WHEN PREGNANCY IS TO BE AVOIDEDIn theory, it should be possible to avoid getting pregnant by using caution during the 5-dayfertile period which includes the day of ovulation. However, there are cases in which the eggremains viable for two days or more or when the sperm maintains its viability for more than 3days, so the time from the 4th day of the high temperature period up to the start of the nextmenstrual period should be considered the period of infertility.*Birth control that relies only on this may result in unwanted pregnancy. Always augment thiswith another form of birth control.

BASAL BODY TEMPERATUREBBT should be taken orally for 5 minutes

Women differ from men in their sexual functions in that they are capable of“getting pregnant”, “bearing children” and “nursing children”.Due to this, women have unique hormones, the conditions of which can bechecked by various external methods. Measuring the BBT is one of these methods.

The Basal Body Temperature (BBT) is the temperature closest to that in the sleepstate, taken immediately upon awakening, before attempting activity or influencedby psychological factors.Ideally, the BBT should be taken immediately upon waking while still lying down. Taking the BBT after eating or drinking, even while lying in bed, will result in anincorrect reading. A correct BBT cannot be taken after getting up and becomingactive.

BASAL BODY TEMPERATURE CURVEThe Basal Body Temperature (BBT) consists of two phases with the day of ovulation inthe middle. The BBT is lower prior to ovulation and higher after ovulation. 1 or 2 daysafter ovulation the temperature shifts into the high range and stays there for about 2weeks. It then drops prior to menstruation. The changes in a person’s BBT can beunderstood by recording the BBT over several months.

Copy the Basal Body Temperature Chart on the reverse side to record your BBT.

The BBT CurveThe BBT curve indicates a woman’s reproductive cycle, her sexual function and health.Recording the BBT over a period of several months allows one to estimate the day ofovulation as well as the date of the start of next menstrual period in order to determinewhen pregnancy is most likely to occur and to use birth control measures if necessary. Inaddition, the information may also assist in the discovery of gynecological disorders orpsychosomatic conditions.It is recommended that an obstetrician-gynecologist be consulted when there areconcerns about the BBT curve or feelings of malaise occur.

DETERMINING THE POSSIBILITY OF PREGNANCYWhen menstruation has not started by the 21st day after the day of ovulation and thetemperature remains high, there is a possibility of pregnancy.

Pregnancy Example

*There are individual differences in the BBT Curve (changes in body temperature). Anobstetrician-gynecologist should be consulted when there is a pattern different from thatshown above.

Normal BBT CurveThere may be individual differences in the elevation of temperatures.

PROPER MEASUREMENTPlace the sensing section of the thermometer firmly against the root of the tongue and use thetongue to prevent its movement. Hold the thermometer to keep it in place and make sure thatthe mouth is closed during measurement.

˚C

Self-diagnosis of measured results and treatment is dangerous. Be sure to follow theinstructions of your doctor.If you believe you are pregnant, see your doctor immediately.

HOW TO TAKE ACCURATE BASAL BODY TEMPERATURES• The Basal Body Temperature (BBT) measurements should be taken orally for 5 minutes

in the case of keeping the BBT chart.• Take your temperature immediately after waking up, before getting out of bed. Do not eat

or drink anything or start moving around before taking your temperature.• As far as possible, take your temperature at approximately the same time each morning.• Place the thermometer's sensing section in the same location when taking the temperature

each time.• Do not open your mouth while taking your temperature orally. Avoid breathing through

the mouth.• Record the reading on the BBT chart after measurement.

The display section is faced upwards.

Root ofTongue

Placement Points

ORAL USE:The mouth should remain closed up to 5 minutes beforeattempting a reading.

• Place the thermometer in the mouth under thetongue so that it rests to the left or right of theroot of the tongue.

• Use downward tongue pressure to hold thethermometer in place.

• Hold the thermometer to keep it from slidingaround in the mouth.
