How to request pcb documentation from Echostar

how do I request schematic document from Echostar? I couldn’t find a proper email to send them a request and don’t know how to convince them to give it to me. Its to create a professional electrical circuit animation video to demonstrate the evolution of Dish network equipment. I have the equipment but it’s hard to tell if it is genuine.

Hello,
