Touchscreen Installation

1. Clean the reverse side of the replacement touchscreen with the supplied alcohol wipe.

2. Cut pieces of the supplied 1/2” double-sided foam tape long enough to cover each edge of the

screen without overlapping.  After the tape is in place on the screen, peel off the backing.

3. Replace the new touchscreen over the monitor in the same manner as the old screen, making

sure the screen is properly and evenly aligned over the monitor glass.  Then clean the front of
the screen with the supplied alcohol wipe.

4. Carefully slide the new monitor into the bezel, making certain that the white edge of the moni-

tor and the monitor wire connections are facing the bottom of the bezel.  Ensure that the
monitor is properly centered, then tighten the hinge screws.  See Figure 2.

NOTE:

  If you removed the joystick on your Elite Edge, carefully return the game to its side and

reconnect the joystick to the connector in the game.  Place the protective bracket in its previ-

the installed screws.  Make sure all wires are secured inside the bracket, then reinstall the 2
screws securing the bracket.  Return the game to its upright position.

earlier.  Also refasten the strain relief cord and the dongle socket ground wire.  See Figure 1.

6. Replace the dongle socket assembly by securing the bolt, green wire and nut over the LCD

mounting plate.  See Figure 1.

wrap.  Also restore the touchscreen controller cable ground wire.  See Figure 1.

8. Connect the touchscreen power cable to the touchscreen controller (See Figure 1) and recon-

nect the Molex connector (orange and gray wires).

9. Connect the LCD power connector (black and yellow wires).  See Figure 2.

10. Reattach the OSD board to the Velcro on the hinge, then connect the OSD cable to both the

OSD board and the monitor.  See Figure 6.  Secure the cable in the twist clamp.

11. Connect the VGA cable to the monitor and secure it with tie wraps.  Also replace the ground

wire.  See Figure 1.
