● Keep the battery away from children. If the battery is swallowed, contact a doctor
immediately.
● Measure temperature according to the directions given by your doctor.
CAUTION
●
●
●
●
Do not disassemble the thermometer.
Do not pull the cord.
Do not splash water over the thermometer.
Do not leave the thermometer in a place where it will be exposed to high temperature, direct sunlight, high humidity or where the ambient temperature is below 0°C.
FEATURES OF CT915
● 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.
Since the temperature data of 31 days (31 measurements) is displayed by a graph, you
can also check the measurement result and date.
● Alarm to notify measurement time is available.
You can measure your body temperature at a regular time every day.
● You can take out and store the probe easily.
You can take out and store the probe easily since it is small in size.
● Antibacterial plastic is used.
An antibacterial plastic is used for the probe.

N Basal body temperature graph
English
BASAL BODY TEMPERATURE
<Basal body temperature is important information from
a woman’s body.>
The body temperature of an adult woman increase and decrease regularly after each ovulation period. That is, the body temperature
remains low until an ovulation period, then
rises after the ovulation period. It decrease
again after the menstruation.
The difference between the high temperature
and low temperature is less than 1°C. The
temperature measured to check the high and
low-temperature periods is the basal body
temperature (BBT). The BBT should be measured ideally in your mouth just after you wake
up each morning.
If you record your BBT for several months, you will observe the temperature change unique
to your body. From the change of the BBT, you can forecast your ovulation period and
menstruation, which allows you to control birth. If your menstruation is not regular, you
can receive proper medical advice based on the record of your BBT from your doctor.
Furthermore, you can forecast a menopausal disorder by observing your BBT. The BBT is
important information for every woman.

[Precaution]
The change of the BBT depends on each woman.
When using the BBT graph, record the BBT continuously for at
least three months and consult your doctor.

Observe the following precautions to prevent a malfunction.
15. Do not store the thermometer in a place where it may be badly affected by atmospheric pressure, temperature, humidity, ventilation, sunlight, dust, salt, air containing sulfur, etc. or where chemicals are stored or gas is produced.
16. Protect the thermometer from vibrations and impacts (during transportation, too).
1. Do not use the thermometer for any purpose other than measuring body temperature.
17. Do not mistake the polarities of the battery.
2. Do not splash water over the body.
18. Do not use the thermometer together with another device.
3. Do not bring the thermometer near strong static electricity, radio wave, magnet, or TV
19. If any trouble is found in the thermometer, turn off the power.
4. Do not use a cellular phone near the thermometer.
5. Do not bite the probe.
6. Do not pull the cord or swing the body with the cord.
7. Do not open or close the body cover forcibly.
8. Keep the thermometer away from children since it can injure them and can be damaged.
9. Do not use paint thinner, benzene, or cresol water to clean the thermometer.
10. Do not clean the thermometer with water, hot water, or ultrasonic cleaner.
11. Do not dip the thermometer in disinfectant alcohol.
12. When storing the probe in the body, wipe off moisture with tissue paper, or a dry
cloth.
13. Never repair, modify, or disassemble the thermometer.

PRECAUTIONS
● Wipe the body and cord with a cloth soaked in neutral detergent.
(Since the body and cord are not water-resistant, extreme care should be taken.)
● Wipe the probe and sensor with a cloth soaked in disinfectant alcohol or neutral detergent.
● Since the probe and sensor are water-resistant, they can be washed in water.
Extreme care should be taken however, to prevent water being splashed over the body
and cord.
