Caution of the removal of the Control panel Section
The two FFCs that connect between the Control panel section and the Chassis section are short in length.
Therefore, they cannot be opened 180 degrees with the FFCs still connected.
Be careful not to damage the FFC or the connector when removing the Control panel section or diagnosing it.
