Since you purchased some of the ebay items, can you field a couple of questions?Yes you can buy separate bases (docking stations). I have two myself.
You could always buy the Pen from your audiologist but then buy another Pen from eBay to save money.
When my audiologist set up the Roger, all she seemed to do was attach the Roger 19 Receiver to the Naida B, then pair the Pen to the Receiver, all of which I could have done on my own. There didn't seem to be any programming involved on the HA side, beyond physically mounting the receiver. Does this suggest that I could get a spare Pen or other Roger device on ebay and simply use it without any audiologist intervention? Unlike the ComPilot, there didn't seem to be specific programming/pairing needed.
Are there any caveats about buying used Roger components on ebay that I need to be aware of?
