side of each of the VESA Monitor Mounts counterclockwise to loosen the VESA
Monitor Mounts.
2. Lift the Monitors straight up and out of the Plates.
3. Place the Monitors screen side down on a scratch-free surface.
4. Remove the Monitors from the VESA Monitor Mounts by loosening all
four Screws on each of the VESA Monitor Mounts, using a Phillips Head
Screwdriver. Remove the Screws, the VESA Monitor Mounts,the Washers and
any Spacers that may have been used for the installation.

place using Needle-nose Pliers. While holding the Plastic Disc, tighten the Hex
Screw, located on the back of the VESA Monitor Mount, using the M5 Hex Key.
(Figure 10)
Note: These Hex Screws can be loosened in order to adjust the position of the
