Replacing the Top System Board Perform the following steps when you replace the top system board: 1. Before inserting the top system board, move the power switch cover forward toward the front of the base assembly. Make sure that the spring in the power switch is fully inside the plastic housing. 2. Insert the top system board, tilting the board to the left and aligning the appropriate connectors with the slots on the base assembly. Be careful to align the power switch cover with the switch mechanism on the board. 3. Gently press the battery pack connector down to place the connector in the slot on the base assembly. 4. Ensure that the inverter card is firmly attached to the top system board, and that the infrared window is attached to the inverter card. The infrared window has a top and bottom. Install the window with the long side with the partial cutout facing the top of the inverter card. 5. Feed the speaker cable between the inverter card and the top system board to the right of the inverter card connector to the board. 6. As you press lightly down on the top system board and the inverter card, slip the bottom corners of the inverter card into the slots in the base assembly. 7. Gently but firmly press on the middle of the top system board to finish inserting the board and to ensure a complete connection between the board-to-board connectors.
