Me too! The manual was missing, we're trying to find a download now, but the "key" was missing. The guy at Sam's told us it was just a magnet so we ripped into an old blown out speaker and took the magnet. Looks funky, but works like a charm!

I just bought the same thing from sams club and am having the same problem.....I can't even get mine to turn on! Can anyone help?

Manual available at www.reebokservice.com.
Plug into surge protector (recommended).
Insure the switch next to where the cord enters the treadmill is on (reset).
Place the magnetic safety key at the center bottom of the console.
This should normally power on the console and let you choose a workout or start the treadmill manually.

I am a Sam's member. They guarantee COMPLETE satisfaction. I know a treadmill is big, but take it back and tell them you are not completely satisfied. I returned a 30in tv after 2 years and now have a 42 for the same price.
