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 monitor

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 previous
