Hi

After replying to you yesterday I got intouch with Polar Uk and stated that the problem in question had started again on the replacement unit. As i only had the unit just less than a year it is still under warranty polar have a 2 year warranty. The person on the phone at Polar sais that he never heard of the problem but told me to wait until he talked to the technical people over there . He came back to the phone and stated that the circuit board had a problem downloading the heart rate information and that polar had a fix for the problem about two months now . If i returned the unit to them they would carry out the repair.

I hope this helps you.
