INSTRUCTION MANUAL FOR CT915
SAFETY PRECAUTIONS WARNING ● Keep the battery away from infants. If an infant swallowed the battery, meet a doctor immediately. ● Measure temperature according to directions given by a doctor and consult him (her). CAUTION ● ● ● ● Do not disassemble the thermometer. Do not pull the cord strongly. Do not splash water over the thermometer.
● CT915 records measurement results automatically. CT915 records data of up to 120 days (measurements). ● Basal body temperature recording mode or all-measurements recording mode can be selected. If the basal body temperature recording mode is selected, the temperature is recorded only one time a day. If the all-measurements recording mode is selected, all the measurement results are recorded. ● You can check the change of your body temperature by graph.

all-measurements recording mode. If the “LADY” mark is displayed, the thermometer is in the basal body temperature recording mode. In this mode, the basal body temperature measured for the first time on each day is recorded. If the “LADY” mark is not displayed, the thermometer is in the all-measurements recording mode. In this mode, all the measured temperatures are recorded. 1) Push the right (s) or left (t) shift switch to turn on (or off) the display of “LADY”.
BASAL BODY TEMPERATURE RECORDING MODE 1. Remove the probe from the body 1) Open the cover and push the rear end (left end) of the probe lightly to remove the probe from the hook. 2) Unwound the cord from the body. 2. Measure the basal body temperature ■ Method of measuring basal body temperature (at a regular time once a day) 1) The alarm buzzer wakes you. 2) Push any one of the switches. The alarm buzzer stops after about 30 seconds automatically.
* If the POWER/MEASURE switch is pushed and held for a while (about 1 second), the power is turned off. When displaying the measure screen while the power is turned on, push and release the POWER/MEASURE switch quickly. 3) Place the probe under your tongue. (See “How to measure basal body temperature correctly” on page 20.) Apply the probe tip (sensor) to the groove at the center of the underside of your tongue and close your mouth lightly.
* The measure mark indicates how many minutes have passed after measurement is started as shown below. Start of measurement After 1 minute After 2 minutes After 3 minutes 3. Store the probe in the body 1) Wipe off saliva with tissue paper, etc. 2) Wind the cord clockwise onto the body by 2 turns and a half. 3) Fix the probe to the hook with a click and close the cover.
the power. If the POWER/MEASURE switch is not pushed, the record display screen appears automatically and the power is turned off 30 more seconds after. the basal body temperature recording mode, the temperature mea* In sured for the first time on each day is recorded automatically, but the temperatures measured for the second time and after on the same day are not recorded automatically.
ALL-MEASUREMENTS RECORDING MODE 1. Remove the probe from the body 1) Open the cover and push the rear end of the probe lightly to remove the probe from the hook. 2) Unwound the cord from the body. 2. Measure the body temperature ■ Method of measuring body temperature (Allmeasurements recording mode) 1) Push and hold the POWER/MEASURE switch for a while (about 1 second) to turn on the power. Fix the probe to the hook with a click and close the cover.
* If the POWER/MEASURE switch is pushed and held for a while (about 1 second), the power is turned off. When displaying the measure screen while the power is turned on, push and release the POWER/MEASURE switch quickly. * To change the basal body temperature recording mode ( LADY is displayed) to the all-measurements recording display ( LADY is not displayed), repeat the operation of “Setting alarm, time, date, and mode” (on pages 6-10) from the first, then select the all-measurements recording mode.
5) In the all-measurements recording mode ( LADY is not displayed), all the measured temperatures are recorded automatically. * Even in the basal body temperature recording mode ( LADY is displayed), you can measure your body temperature by the above method. Your body temperatures measured after your basal body temperature is measured are not recorded, however. 3. Store the probe in the body 1) Wipe off saliva with tissue paper, etc. 2) Wind the cord clockwise onto the body by 2 turns and a half.
● You can check the change of your body temperatures in 31 days (31 measurements) at a glance. 1) Push and hold the POWER/MEASURE switch for a while (about 1 second) to turn on the power. (The record display screen appears.) 2) The temperatures recorded up to now are displayed in graph on the lower graph display unit. In the upper value display unit, the temperature and the date of the blinking bar are displayed alternately.
3) Move the graph forward or in reverse with the right (s) or left (t) shift switch and check the temperature and date of each bar displayed on the value display unit. * If the SET switch is pushed, the unit of the vertical axis of the graph changes (0.05°C or 0.2°C). Select either unit to check the change of your body temperature. [Unit: 0.05°C] [Unit: 0.2°C] SET Detailed graph in the range of 1.

BASAL BODY TEMPERATURE The body temperature of an adult woman becomes low and high regularly after each ovulation period. That is, the body temperature keeps low until an ovulation period, then becomes high after the ovulation period. It lowers again after the menstruation. The difference between the high temperature and low temperature is less than 1°C.
English N Basal body temperature graph High temperature period Ovulattion Day Low temperature period [Precaution] The change of the basal body temperature depends on each woman. When using the basal body temperature graph, record the basal body temperature continuously for at least three months and consult your doctor.
