Query: The directions are terrible

I have had this heart monitor for less than a year, and I am already having problems with it. I want to find how to get out of the loop of Lap & Split, I can't clear the review mode so I can't record any new workouts. There is NOTHING in the directions on how to fix this problem. My spinning teacher couldn't even help me.
