I didn't try to take out the gel yet, but I think there's a small opening on the cover which you suppose to open and then pour the gel into the funnel and into a bowl. Then put the bowl in the microwave oven to re-dry the gels.
Since yours is new and the gels are still orange, there is no need to do so. Just use it.
As long as the reading don't go over 50, you are fine.
