Wedge the flat end of a plastic opening tool between the front panel assembly retaining clip and the outer case (highlighted in blue).

Carefully pry the opening tool upwards to release the retaining clip securing the upper portion of the front panel assembly.

Do not use excessive force when releasing the retaining clip. The plastic is very weak and may snap easily.

Run the flat edge of a plastic opening tool around the perimeter of the front panel assembly to release the remaining retaining clips.
