It's a simple process.  It is very important you save the box and packing material when your machine arrives.  Inside your box when it arrives are several important documents. The first is a guide that will help you pack the equipment for return.  The second is a return shipping label that you attach to the outside of the box.  After you have attached the label, call FedEx and they will pick up the equipment at no charge to you.  
If you have any questions about the process or need assistance in making arrangements with FedEx, please call one of our Patient Care Representatives at 1-877-301-4276.
