7. Disconnect the power supply unit (smaller board) from the mainboard.
8. Connect 6V PSU Hub 2/Hub 2 Plus to the mainboard using the eight-pin
connector between them. Do not warp or bend the antennas while replacing
the board: this can cause the device to malfunction.
Please note: the board contacts should be plugged in the bottom row of the
connector (closest to the board). When connected correctly, the boards are on the
same level.
