eCross-point buttons

The cross-points in the auxiliary bus control block are arranged in two rows: an upper row (1st row) and a lower row (2nd row), and are allocated to the buses selected with the AUX delegation buttons. The 1st row contains the cross-point buttons for unshifted buses, and the 2nd row contains the cross-point buttons for shifted buses. When the DME 1V/K to 4V/K buses are selected with the AUX delegation buttons, the 1st row cross-point buttons are for the currently showing side of DME, and the 2nd row are for the reverse side.

By holding down the [2ND] button and making an AUX delegation selection, you can allocate the 2nd row to a different bus from the 1st row.
