•    When your LH surge is first detected, the test will display a static smiley face and this will continue to be displayed constantly for 48 hours, indicating your 2 most fertile days.
•    You cannot do another test while Peak Fertility is shown on the display as the holder will not be able to read it. You can save any remaining test sticks to use in a future cycle if needed.
•    Don’t remove the batteries to try to reset the holder, if you do this you will break the holder and you won’t be able to use it again
