I was having issues with black king(s) reading on squares g2 and g3 of my DGT Bluetooth board. I was able to fix this issue by making an adjustment on the circuit board. This adjustment was suggested by the DGT support personnel.
1) Remove the sticker from the long panel access (states it will void your warranty).
2) Remove the two 2.5 mm Allen screws.
3) Lift the cover (a small screw driver place in a screw hole will help lift it out).
(Now's a good time to ground yourself :-)
4) Turn the circuit board over
5) Facing up is a small, cream-colored adjustment screw (See picture below).
This screw adjustment is so sensitive, that will will go to ghosting every square, even though no pieces are on the board, to not reading at all (with all the pieces on the board) in 1/4 turn (i.e., an eighth turn either direction).
6) To increase the sensitivity turn it counterclockwise (I suggest initially trying 5-10°).
After making the adjustment place your pawns on the board and move a pawn toward the each corner of the square. If it ghosts to the adjacent square, you set the sensitivity too high. When everything is just right, you will get a really snappy move response and no ghosting issues.
However, DGT is aware there can be ghosting issues and that is why they place a colored dot on the bottom base of the chess piece indicating a slightly different frequency (i.e., if you experience ghosting don't place two pawns of the same dot color together).
