U6: How to install User Popcon Characters?

[Timeless]

Hello

First, thanks so much to the abipod people for the site and lebellium for your review of the YP-G50 (for which I was tempted until I realised that I just wanted to play music!) and the YP-U6.

I just purchased an U6, I have downloaded the U5 Popcon pack hoping it would be compatible but it doesn't seem to recognize any user popcon. I also tried putting it in a folder, it just shows the built-in characters. So I guess it uses another format, but which one and how to install it? Or how can I find out?

Any help would be appreciated — the tiny manual doesn't say anything about Popcon — though it's not really urgent ;)
