Attaching the Tilt and Swivel Base
Before you attach the tilt and swivel base, cover your work area
with a blanket or foam pad to avoid scratching the monitor.
Then follow these steps:
1. Carefully set the monitor face down on the padding so the
bottom of the monitor is facing you.
2. Locate the four sets of hooks on the top portion of the base.
3. Hold the base so the hooks are turned down and position
the base next to the bottom of the monitor.
