Make sure the hand controller is fully charged. When you're charging, check that the inductive charging plate is active and that the center of the hand controller is correctly positioned at the center of the charger. The center of the hand controller is located between LED lights 4 and 5. As the hand controller charges, the LED lights will light up one by one. When fully charged all the lights go out.
To pair the hand controller with the board, attach the magnet key to its designated area at the back of the board. Press the hand controller throttle all the way down until the LED lights begin to flash. When they stop flashing, the hand controller is paired with the board.
