Slide the point of a spudger under the black antenna cable until it's snug against the connector, and pry straight up from the board to disconnect the antenna cable.

Follow the same procedure to disconnect the white antenna cable.

To reinstall these antenna cables, hold the connectors in place and gently press them straight down. The connectors “snap” into their sockets much like the metal snaps on a jacket.

Make sure to plug each cable into the correct socket during reassembly. The white cable should plug into the upper socket, while the black cable plugs into the lower.
