Error icon on ovulation test
I purcahsed the advanced digital ovulation test, as part of a kit with 10 tests. It worked fine the first 3 times, but now the monitor shows the manual (book) icon, which does not go away. I removed the original test stick, but to no avail, the icon remains.
Is there anything I can do? If not, can you please replace my tester so that I can also test the remaining sticks? It was quite an expensive kit, so a bit surprised to see this tester fail so quickly.
