Hi, I have a fenix 8 watch I use for golf. Have just bought the ct10 sensors but for some reason they won't pair. It comes up saying "approach ct10 sensors use open connection". I click the tick and then says "club sensor detected. Pairing". But then doesn't pair and says "pairing failed". I have followed the instructions and doesn't Have also changed the battery in one and still says the same. Does anyone have any ideas?
