In this step we will remove the inner circuit board and locate the caps we will be adjusting.

Once the top and bottom plates are removed the inner board will slide out with some slight pressure. Once the boards out you just want to find the 6 small variable capacitors towards the middle of the board.

Many times, a wire like that is added during a production run to address a mistake in printing the board. Also, many times the mistake in the board is addressed in later models so wire is no longer needed. Compare board revision numbers.

What if the inner board won't come out - even with significantly more than "slight pressure"?

there may be screws or little plastic catches holding it in... if not pry it away from the board (in one piece) and make a new container, with perhaps a better aerial!
