For models KEEMUX-Sx-O (with OSD):
1. Make sure the KEEMUX-Sx-O is completely disconnected from all computer components. Be sure to
unplug the KEEMUX-Sx-O from the electrical outlet.
2. Remove the two philips-head screws from the underside of the KEEMUX-Sx-O that hold the plastic
case together. Remove the 4 torx-head screws from the underside as well. These hold the lower circuit
board to the plastic case. Turn the KEEMUX-Sx-O back over and set it on a firm and flat surface.
3. Remove the top half of the plastic case from the KEEMUX-Sx-O.
NOTE: Before proceeding, it is important to discharge any static charge you may be carrying by touching any large metal object
(away from the KEEMUX-Sx-O).
4. Firmly grasp the front and rear panel and slide the entire assembly out of the lower case.
5. Remove the jack screws from the video and monitor connectors on the rear panel. Remove the rear
panel from the assembly.
