I would say that P1, P2, P3, P4 are place holders for programs, but they represent the order in which these programs are cycled through if you were to use the hard buttons on the HAs to cycle through them. Meaning you’ll start out with P1 on boot up, then if you cycle up, you’ll go to P2 next, then another up click will take you to P3, another down click will take you back to P2.
If you didn’t have any TV Adapter or ConnectClip Remote Mic, then an up click from P4 will take you back down to P1 (circular connection). Similarly, a down click from P1 (without the TV Adapter or ConnectClip RemoteMic) will take you up to P4.
If you have the TV Adapter and/or ConnectClip Remote Mic, an extra program placeholder is created for the TV Adapter and another for the ConnectClip Remote Mic, and these will be inserted between the P1 and P4 connection.
When you choose and assign one of the built-in programs from the Genie 2 menu for a program place holder, Genie 2 will automatically assign a name to it. For example if you choose VAC+ in P1, then P1 will be assigned the name General. If you also choose VAC+ in P2, then now P1 will be called General 1 and P2 will be called General 2. Let’s say if you choose NAL-NL2 for P3, then P3 will be called General 3.
If you choose and assign Speech in Noise for P2, for example, then P2 will be named Speech in Noise. If you also choose Speech in Noise for P3, then now P2 will be called Speech in Noise 1, and P3 will be called Speech in Noise 2.
You can edit any of these automatically assigned names to anything else you want. For example, you can change General 1 in P1 to “Jim’s Most Used” or something like that. Well not YOU in the ON app, but your audi in Genie 2. It appears that you can edit 2 of these program placeholders to have exactly the same name too, as long as it’s not a blank or space (which are not allowed). If they have the same name, then the only way to be able to tell them apart is to see which one is assigned to which P. For example, we know that program “Same Name” in P3 is different than program “Same Name” in P4 thanks to their associated assignment to their respective P.
You cannot edit the name for the TV Adapter or the ConnectClip Remote Mic, however. They don’t even appear as programs alongside with P1, P2, P3, P4 in Genie 2. They appear in a different menu as Accessories. If you have the EduMic, it seems to be bunched together with the TV Adapter. I’m not sure why Oticon decided to bunch them together because I think there’s a possibility you can own both at the same time.
