If you don't know the weight of your wheelchair and you'd like the scale to store it so it will display only your weight, you can do that in the settings of the Lilypad app for iPhone. Make sure your wheelchair has only the things on it that will be on it when you use the scale. Then open the Lilypad app (with nothing on the scale), wait for it to connect and say "Ready," then wheel the wheelchair on. When the wheelchair is on, tap the settings wheel (upper right hand corner), then tap "Store Wheelchair Weight." The app will go back to the main screen and say "Stored." You can now press "Weigh" if you want to use the scale. The app will continue to store the wheelchair weight if you close the app and even if you turn off your phone.
If you already know your wheelchair weight and just want to input it, or you'd like to weigh your wheelchair and know how much it weighs before you store it, check out our article called "Input Wheelchair Weight on the Lilypad iPhone app."
