JP1 Remotes

I have the Panasonic DMR E85 DVR. I need the codes to perform the functions of its remote using a RD-15-2116. I have only been able to find an upgrade for the older DMR E80, which does not have all the functions I need. Where would I find the E85 codes? I realize that I can teach the 2116 the functions of the original E85 remote, but that takes more memory and, in addition, my 2116 seems to have ADD, or some other learning disability-- it often fails to learn its lessons.
Can anyone help?

I am using the latest RM and IR.

Thanks
