replaced wearlink strap, still not working
I got a Polar FT4 about six months ago. About a month ago the heart rate readings starting getting really inconsistent and crazy--jumping from 115 to 250 for no reason etc--and then stopped working entirely.
I figured it was my Wearlink strap, as I hadn't realised I was supposed to wash it frequently, so I thought the sensors were probably corroded.
I got a new strap and attached my transmitter thing to it, but the watch still reads zero heart rate. I've tried tightening the strap and moistening the contacts but it doesn't seem to make a difference.
Is there anything else I should try before writing the whole thing off? I'm still in warranty but I can't find the darn receipt so I can't send the thing back...
