I have the Sportline 4065. I am unable to get the heart function mode to operate properly. When I select the heart mode it show the range mx and I can select the R F(?) don't know what the F is. However when I press and hold the button below the display nothing happens. It just continues to to show either the mx or the F......What do I need to do????
