DuoFertility

This icon can be used to cancel anything that you have entered into the reader
If you have entered something into the DuoFertility reader by mistake, don't worry, you can easily cancel it! All you have to do is select the “cancel” icon (see left), it will flash orange and the icon of the last function that you entered will flash red, indicating that you can now cancel that entry.

To confirm this, you must scroll clockwise in the scroll area until the scale which is displayed turns green, and then press the central button; if you do not scroll far enough, the bar graph will stay dark, and pressing the button will not cancel the last entry. Once an action has been cancelled, the reader will automatically revert to displaying your fertility status on the scale.
