I just replaced the batteries on both the watch and the HR monitor belt. The watch works great, but it is not finding my belt! I have tried paring it - says "device not found" I have put the battery in both directions (like it says to in the manual) still nothing! And it doesn't pick up my heart rate! What else can I do?
