Affixing the Arm Base to a Tabletop

There are two different configurations of the Arm Base, illustrated in Figure 5-3. On the left of
Figure 5-3
is the configuration of the base for a table that can accept the shim at a deep
position under its surface. This may be required if there is a lip at the table's edge, and is the
default configuration that the system generally ships with. The bolt is fully tightened when the
unit is shipped and places pressure against a shiny steel shim that abuts against the
underside of the table.
Be careful while handling the Arm Base's shim as it may have sharp
edges around it centermost hole.
The Arm Base configuration on the right of
narrow ledge on the underside (as small as 18 mm, accommodating tabletop heights of 60 mm
– 6 cm or 2 3/8"). This configuration is created by removing the long bolt that presses against
the shim, loosening the screw at the bottom of the base, reorienting the L-shaped bracket so
that the short portion is now perpendicular to the base, and screwing the bracket back to the
base. The bolt must now be turned through the short portion of the L-shaped bracket in order
to meet and apply pressure to the shim on the underside of the table. Some light viscosity oil
may make the turning of the bolt go more smoothly, but keep in mind that oil will result in
discoloration of the paint on the LCD Arm Turn the bolt through without using oil if possible.
To install the Arm Base, use the large supplied L-shaped Allen wrench to unscrew the black
bolt that has a hexagonal opening in its end. It will have to be unscrewed enough to allow the
shim perched on its end to fit under the table edge, as the shim will eventually be the point of
contact between the bottom side of the Arm Base and the underside of the table. The large
underside of the Arm Base will be the point of contact with the Table's top. Place the base in
position, covering the biggest surface area of the table as possible and with the shim as deeply
under the table as possible. With the center hole of the shim on top of the bolt, begin to tighten
the bolt while holding the shim so that it does not fall off of the bolt. Pressure will eventually
hold the shim in place. Tighten as securely as possible.
