I can not get the recall function to come on. when I press that button all I get is function; set; lab/split flashing....but no recall phase so i can see my splits. the recall did work a few times but now i must have hit something so recall does not come up. I have the woman's Ironman triathlon t5k186. I would appreciate any suggestion to fix this problem. I realize that operator error could be a factor but i am following the directions. thanks
