Ramsey Electronics SHA2 - Manual (Page 18)

The battery snap is the last part to be installed. The red lead goes into the
hole marked with a “+” sign and the black goes into the “-” hole. You can
tin the leads by twisting them together and melting some solder on them
or you can simply twist them, put them through the board, and solder
them. It’s up to you. Just don’t tin them so much that they don’t fit through
the holes in the board.
That’s it! But wait, before you grab a battery and fire up your kit let’s check a
few things. Mainly check the orientation of the ICs, diodes, and all those
electrolytics. We don’t want anything to go “pop” when we apply power, right?
Also check your solder joints for any that are less than perfect and make sure
that all the solder connections you see on the back are supposed to be there.
Bridges can be dangerous to your circuit. Be sure none of your clipped off
wires have lodged between the connections on the back. When you’re
satisfied we’ll move on and give your headphone amp a try.
