Keyboard Drawer holes (as shown in Figure 1b) should be drilled for
the specific keyboard size. Care must be exercised to use the
specifications in Figure 1b regarding drill size and hole depth.
To offset viewport and keyboard drawer, please call customer
support at 1-800-730-6682 for special instructions.
If the worksurface is prepared for Retrofit Kit & Keyboard Drawer
Installation, skip to Step 3. Otherwise, please prepare your worksurface
to the specifications shown in Figure 1a for Viewport & Side Assembly
milling/drilling.
The retr ofit kit can be installed in almost any work surface. The kit is
designed to attach to a work surface that is 1-1/8" to 2" in thickness. Thinner
work surfaces may requir e some build-up of material for pr oper installation.
Glass work surfaces are not recommended. If your countertop is a solid
material such as natural granite or marble or a fabricated solid surface such
as Corian, you should use a professional fabricator to cr eate the opening and
surface mounting anchors requir ed for your kit.For ward a copy of the
boring pattern and hole size cut out to a professional fabricator.

FIGURE 3
As shown in
Figure 3, attach Left Keyboard Hanger securely
to the underside of the worksurface using three (3) Screws
(Ref. #8) and one (1) Screw (Ref. #9). Repeat procedure for
other side.
IMPORTANT: The longer of the screws (Ref. #9) passes
through the tubular section of the Keyboard Hanger allowing
the assembly to be leveled by either tightening or loosening the
screw. Adjusting the screws allows you to fine-tune the action
of the keyboard drawer.
Step 7
Install Trim Ring by snapping pieces together (Ref. #12 and
#13), lowering into cutout, and attaching with four (4) screws
(Ref. #11).
Step 9
Adjusting Your Monitor: The Monitor Support adjusts three
ways — height, angle, and forward/backward. Adjust it so that
you have a comfortable viewing angle of the monitor when
you're in a normal working position. Push Outward Locking
Tabs back to unlock keyboard drawer. See Figure 4. Remove
the keyboard drawer and the glass. Lower the monitor through
the viewport opening while allowing the wires to feed through
the back of the monitor support. If the monitor is too heavy,
make sure you get assistance.

1. Install monitor as high as possible without loosing the
appropriate viewing angle.
2. Screen should point slightly above user's face (bottom
edge of monitor is nearer to the eye than top edge).
Determine the modification necessary to accomplish the
preferred viewing angle. To make angle adjustments, move
either the top or the bottom Tracking Block assemblies
independently of each other. For oversized monitors, a good
starting point is 11 spaces down in front and 9 spaces down
in back.

Downward Gaze™ Monitor Installation
Step 10.2
Once the angle is adjusted, adjust the height by raising or
lowering both upper and lower Tracking Block assemblies
the same number of spaces.
Step 10.3
The bottom of the screen should always be closer to your eyes
than the top.
Step 10.5
After you achieve the desired height and angle, you can fine
tune the viewing distance by sliding the carriage forward and
backward. Each time you make an adjustment, reinsert the
Male Tracking Blocks. When the adjustment is completed,
install the Security Screws.
