McIntosh C200 Preamp Activating Inputs - HELP

Okay the manual tells you how to easily turn off unused inputs so that you don't have to scroll thru them.
What it DOESN'T tell you is how to turn them back on because the manual is Wrong !!!!!!!You can't scroll to the input like the manual wants you to believe.
Please help, maybe I am electronically impaired but I don't think so!

You can use the "factory reset" function to start over. Alternatively, you can give Mc a call to see if they have a shortcut that I'm not aware of (my C50 requires a reset). Good luck!
