I had kind of a similar experience with Minimed. I got a new pump which has the integrated CGM reciever, called a Paradigm Revel. Also included in the box was a "Medi-Link Real Time Transmitter" and a box of sensors. But no call from Minimed on how they worked together, which part performed what function, no training set up. Nothing. I put them all to the side, thinking they would call or email eventually, but three months went by without any contact! So being the passive-aggressive engineer that I am, I read all the manuals and figured out how to use it on my own. Then of course, I became compeltely frustrated and finally emailed them and told them I got tired of waiting to be trained and either wasn't using it right or it was useless, and they responded and said my doctor's office was supposed to train me. Would have been nice if at some point someone had mentioned that to me.
So call your doctor, but the "parts" that you need are: the sensors,(this is the small piece that goes under your skin), the Medi-Link Real Time Transmitter, (which connects to your sensor, is reusable), and the pump/receiver, (which receives the transmitted information and displays it for you.) By the way, the Transmitter-sensor set, (when connected together) pulls out at the slightest touch and the sensors are VERY expensive, so I highly recommend buying some IV cover pads that can be purchased online for about $40 for 100. Way worht it!
Good luck and feel free to contact me if you get confused at all. I've been confused a lot!
