Anybody using a New Balance via active pedometer?

Options
I just bought one last night and found the instruction manual (and on line help) to be sorely lacking. I am able to program the time, date and unit of measurement, but it will not allow me to input my stride length or my weight. Frustrated as heck right now because without the stride length or weight input, it is basically useless for anything other than tracking steps. I paid $40 for the darn thing (then found it online for cheaper- Grrr!) and would like to be able to utilize it. Right now I'm thinking of just returning it and getting my money back.

Does anybody have trouble shooting ideas?
