While the front panel is still warm, use the edge of an opening tool to pry it from the headphone jack side of the front panel assembly out of the Nano.

Do not attempt to pry out the front panel assembly from, or insert the opening tool into the left side of the display, as the display data cable is right underneath and may be damaged in the process.

Continue prying the perimeter of the front panel assembly out of the outer casing, being careful not to damage the display data cable held under its left edge.

If the front panel is excessively difficult to lift out of the outer case, reheat the area and try again.
