forerunner 405: Hartbeat impossible high

Former Member over 15 years ago

Hi,

Yesterday, while running with my Forerunner 405 (excellend device !!) my hartbeat was skyhigh. It was so for over 5 minutes. And no, the problem was not with my hart :)
Anyone who has experienced the same problem? What did I do wrong of is my device gone crazy?

Hope to hear !!

same problem with 405CX.
half an hour OK, then at once heartbeat 210-220.
Keeps on for a few minutes, suddenly, while running at same speed, hearbeat falls down to normal level (170-175)

Hope there is someone with a good solution.
I see very much problems of the same kind
