I need the manual for the "New Balance 5k 5200 Stationary Bike". I see your website has the 5100 manual but I need the 5200. Any assistance in this matter would be greatly appreciated. The battery compartment has rusted. It good be from batteries, I am not sure. This bike was given to me in exchange for some work that I performed. Also, I believe it may be missing parts that is why I need the manual. I may have to replace parts. Again, any assistance given is greatly appreciated.
