Subject: memory backup battery mod

Hello everyone.

I hope y'all don't mind if I begin my first post with a question. I have a Poly800 mk1 that I'd like to add the battery backup mod. I looked through the files here and found the mod text, but after having looked over the schematics I came across something I don't understand.

In the text the instructions read "In the upper left corner you'll find Resistor R1 and Diode D1. Remove these. (Just cut the legs, but leave as much as possible of the D1 legs, see next steps.). The battery must then be connected by wires, the plus to the junction between R1/D1 and the minus to the other leg of D1."

I may be missing something but since R1 is no longer on the board, where is the + voltage of the battery going?

Just to be clear, I haven't opened my Poly 800 up yet to check the traces. I'd just like to be certain that I have the instructions correct before doing any cutting/soldering.

Thanks in advance.
