Remove the insulation from four 1.5" (38 mm) lengths of green
hookup wire.
Install the bare wires on the bottom of the front panel PC board,
using the four pads below the large rectangular hole (Figure 5-16).
Solder and trim the wires on the top side of the board. The wires
will be connected to the optical encoder, Z1, in a later step.
Figure 5-16
Remove the protective plastic film from the face of the LCD. Be
careful not to scratch the glass. Caution: Do not peel off the LCD
glass, just the thin protective film. The LCD will not be usable if
you lift the glass itself.
Insert the front panel PC board assembly into the front panel. The
pushbutton switch caps on both sides of the LCD should protrude
slightly as shown in the side view, Figure 5-17a.
Note: the board/panel assembly will not be rigidly held in place until
it is mated with the RF and Control boards in a later section.

A 1/4" (6.4 mm) standoff on the PC board should now be visible
through the hole just to the left of the encoder mounting hole. Secure
the panel to this standoff using the 4-40 x 3/16" (4.8 mm) flat-head
screw as shown in Figure 5-17b.
