I have probably screw things in my new HRM pro plus strap. I thought I had to remove the white paper to allow the contact of the plus side of the battery. When I did it, the metal part of the piece came out together.
I realized that it wasn’t too be removed but to help the battery become loose when it was to be changed. Now I don’t know if it has a correct way to be attached back to the top side of the piece so it can correctly contact internally with the sensor. How should it be aligned in regards to the contacts?
