Actually, I looked up the model numbers and it looked like #2 on the right is the Blue-Tooth module.

Thank you so much for posting this. I just bought the same model and got frustrated trying to turn off the wifi. Call me weird, but I can feel it when it's on, so I avoid wifi whenever possible. I think this radiation is one of those things that people will eventually wise up to, but it will take a few years. This video says there is also a 3D emitter, so maybe that was the second one you took out.
