NOTE: If you want the arm to be shorter, attach the upper arm directly to the base.
Step 6: Attach the base covers and lower arm.
Route the monitor cables along the upper arm, then loosely secure the cables to the upper arm with
the cable ties. Do not over-tighten the ties. If the ties are too tight and you try to remove them, you
may damage the monitor cables.
Squeeze the tabs on the lower arm cover to remove the cover, route the monitor cables along
the bottom of the lower arm, then replace the covers.

Caution: Before you tighten the cable ties, adjust your monitor to
the highest position. This will leave enough slack in the cables for
monitor movement/height adjustment.
