Disconnect the membrane keyboard (flex-foil connector on copperside of printed board) 3. Bend the cabinet leftwards downwards 1, while bending the CD-door rightwards upwards 2 The procedure appears to be tricky at first, but force needs to be applied with thumb and middle finger only.

Remark: Don�t worry about applied force - both parts have a solid design. However, do not use screwdrivers or tools like that. Sharp edges might damage hinge or cabinet part.
