This is the OPTIX AUTOMAX Optical Flow positioning Sensor control board.
Optical Sensor Removal
The Optical Sensor Lens, is held in place with a snap on cap. Press the clips inward and lift the cap off at the same time. A second set of hands is really helpful for this.
The Optical Sensor Board is held in place by 2 plastic clips and 3 positioning pins. Press the clips outwards.. very carefully. Again, another set of hands will really help. Have someone lift the Board up off of the pins a soon as the clip clears the board. Don't stretch the plastic clip to far, it could break. The board should now just lift up and off.
