Help newbie - Setting up RTC v battery


I appreciate your understanding that I’m a (real) beginner with the hardware world. Please can you help me on how to connect RC2030 Battery to the FEZ main-board, I got the extender. I know that I have to use Socket Z (2), and I am confused with the red/black wires…which pins should I use?

Kindly, see the attached images.


Thanks a lot again @ andre.m , just another question please.

After connecting vbat, the code here is what I need to setup the time?

Thanks a lot , I really appreciate your time.
