Step 2: Measuring your temperature
1. Use your Daysy every morning before you get out of bed. To do so, remove
the protective cap and briefly press the activation button once. Your predicted
fertility status will be displayed.
2. Press the button a second time and the activation ring will flash in a clockwise
direction. You can now take a measurement.
3. Place the sensor as far back as is comfortable under the right or left side of
your tongue and then close your mouth.
4. "Beep-beep" means that the measurement phase has successfully completed.*
5. The confirmed fertility status displayed after measurement is valid for a
maximum of 24 hours, or until you take the next measurement the following
morning. You can view your fertility status again later in the day by pressing
the activation button once briefly. The next day, your Daysy switches to the
predicted fertility status before your measurement.
* If you hear a "grumble-buzz" sound instead of a "beep-beep", it means that
the measurement was unsuccessful, and you will need to try again.
