Pro-form HRM help

I use Chrono setting when I work out.
You press and hold "Set" to clear this our to begin each workout new.

When I want to check my calories burned, I just check over on "Memory".

After I am finished with the workout, I clear out both the Chrono and Memory sections.

Yes, I use both. Sometimes I hang the watch on my treadmill but if I am doing videos or something then I wear it.

I have been using the timer part when I work out. I guess I will have to try the chrono part tonight. :-D I make sure to reset the timer and the memory after each workout also.

Yes, you need to wear your chest strap obviously. Like someone else said, if you are biking or something like that you can put the watch on the handlebar.
Yes, pressing ST./SP./+ will begin your Chrono workout. You do not have to press it again to stop it and save your calories burned. You can let it keep going and check the memory. For example, when I run I keep it on Chrono mode because I can see my time and also my Heart Rate. While running, occasionally I want to check my cals burned, so I just switch it over to Memory to take a quick check then I put it back on Chrono to see my time and HR again.

I was probably doing something wrong, but in Timer mode I had to set a cal and time goal. The first time I used it I set my cals at 500 (not really knowing what I was doing) then went on a 7 mile run. The monitor had stopped recording when it got to 500 calories or whatever goal time I had it set on. In chrono, I can keep going without having to reset my “goals” for it to record.
