I know I am too late to respond.
It is only because I was struggling once as a beginner also that I would like to post a picture of the visual differences between the on and on in.
Mind that the Roger On In has a hole on the back you can push with a pin. The ON lacks this hole.
On the other hand the label on the back also tells the model:.
This hole is to place the licenses in your HA’s. You can also check in the same way to see if the licenses are on board of the Roger On In as when you push it with a pin it will let you see how many there are on the Roger left/ not transmitted.
If your (Roger ready) HA is direct near the Roger and in coupling mode the license will be transferred one at a time by pushing the hole. In the same way you can transfer them back to the Roger
If the licenses are used or not on the Roger anymore it will show you the 0 if you push the hole.
So by using the Roger On and no licenses on you HA installed the Roger will not connect/ be usable.
Hope this makes it easy for people who want to know.
