Intel®SmartDisplayModuleIntegration:
1. Place the monitor face down on a flat even surface that is larger than the monitor screen. Use a sturdy table that can easily
support the weight of the monitor. To avoid scratching the LCD panel, always place a soft cloth, such as a blanket that is larger
than the monitor’s screen area, on the table before laying the monitor face down. Make sure there is nothing on the table that can
damage the monitor.
2. Remove the SLOT COVER and note that when using Intel® SDM-L type option board, the CENTER RAIL will also need to be
removed. Reverse the process to re-attach
3. Gently push in SDM-S, Raspberry Pi Compute Module IF Board or SDM-L module until you feel a slight click.
4. Screw in module using SLOT COVER screws if necessary
