This is an extremely complicated piece of machinery. I have not gotten it to work the way it is supposed to yet. The instructions are "Yeh" long, with sub-function instructions that are not clear. I even called the company and their technitions had to look up the instructions and they were not sure how to set it up. I'm a senior citizen, but not a dummy. I want to use the watch predominately as a pedomiter, but it cuts off after a minute. I have tried to set it up like the instructions say but it is frustrating. Too much of a good thing. Sorry. Not satisfied, but I'll keep trying.
