f. Stereo upgrade female headers: If you are installing the Stereo upgrade then dig out the
three female headers from the stereo kit bag. There are two 4-pin headers and one 7-pin
header. Once again, there are no markings on the board for these parts so use the pictures
as reference. As you solder them in make sure they are exactly perpendicular to the PCB.
Also make sure the bottom of the headers are flush with the surface of the PCB.

g. Stereo upgrade male headers: If you are installing the Stereo upgrade you need to install
nine sets of 2-pin male headers on the main PCB. The Stereo upgrade kit comes with two
lengths of male header. Break off 9 sets of 2 pins each, starting with a piece of header that
has an even number of pins. (This will ensure you do not end up with a 1-pin header.) Solder
them in the locations: CAL1, CAL2, CAL3, CAL4,CAL5,CAL6,CAL7, J5, and J6.
