You’ll have to transfer the licenses back in to the Roger iN, otherwise you’re done.
I’ve bought a standard Roger On, and 2x Roger X’s AND a Roger Installer. You plug each Roger X (has to be over Serial No 1744) into the installer, then place the HA on it. It then transfers the licence into the HA. Repeat for the othe Roger X & HA. At this point the Roger X’s are worthless bricks.
You have to reverse these processes to get the licenses back in the Roger X’s. If you lose the HA’s, for example, your done for.
Phonak Roger are cynical regarding licensing
