Disconnect the antenna cables

Use a pair of blunt nose tweezers to pull up and disconnect the black and white antenna cables from the daughterboard.
Grab the cables at the metal ends and not at the cable itself to avoid damaging the cables.
During reassembly, these can be tricky to reconnect. One at a time, hold each connector in place over its socket and press down with the flat end of a spudger. The connector should snap into place.
