Using a PH0 Screwdriver remove the three silver screws in the middle ring of screws.

Do not remove any of the 3 black screws in the recessed holes or the 3 silver screws nearest the back lens.

Lift the orientation ring. There are some felt pads on the lower lip that make it a little stiff, but it will lift out.

Note that one of the FPC is connected to the orientation ring.

Note that one of the plastic tabs has an orientation pillar that fits into the small hole near one of the screws.

Be very careful if you disassemble the orientation ring. There is a sping loaded detent roller that is difficult to re-fit.

Screws: 3@ M1.6 x 4mm (white threadlock)

FPC Marking: XL1406_FPC_ENCODER_FPC_Rev03 UFK144513
