Use your Daysy every day after waking up and before you get out of bed.
Please be sure to sleep 1 consecutive hour immediately prior to measuring.
1. 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 until
midnight. 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.
