I have the Sportline 910. When I set up the watch it works like normal UNTIL I set the alarm, then the pulse rate will not read, mine or anyone elses. Any ideas why this happens?
I have pressed all four watch buttons to reset the watch and same thing happens, works fine until I need the alarm, then no more pule reads.
