Difficulty: Easy (~10-15 minutes)

Tools required: long T15 driver

Unplug all cables. Slide the grille upwards to remove it. Remove the black plastic film around the display. Unscrew 7 T15 screws: 4 in a horizontal line above the midrange drivers, and 3 at the bottom, the centre of these being deeply recessed. Do not unscrew the upper two remaining screws.

The rear cover can now be removed: carefully unplug all connectors from the main board, and unscrew it from the chassis moulding.
