Follow the instructions of the onscreen prompt in the upper part of the screen. When you finish,
the prompt will say "Joystick calibrated."
Note:
When prompted to center the joystick, put it in the neutral (resting) position (the
marker may not be centered on the screen).
When you calibrate the throttle, push the trigger button, not the throttle button.

Joystick Service
The joystick controls the direction of flight and operates the weapons. See Figure 30 on page 53
for an exploded view of the joystick. Perform the following steps to replace the Joystick:
1.
Remove the four (4) T-25 Torx screws that secure the Joystick assembly in place.
2.
Carefully lift the assembly straight up and disconnect the two wire harnesses and the ground
wire.
3.
Reverse these steps to install the new Joystick. Be sure to reconnect the ground wire.
Replacing Joystick Grip
See page 53 for an exploded-view drawing. The grip assembly is designed to be replaced easily,
with no need to remove the joystick from the cabinet. Do the following to open and remove the
grip assembly:
1.
Remove the four (4) Torx security screws from the left side of the assembly, and remove the left
half of the grip assembly (see Figure 16).
2.
Disconnect the Molex connector inside the assembly.
3.
Remove the Torx screw on the right side of the assembly, and remove the assembly.
4.
Reverse these steps to replace the grip assembly.
5.
Refer to the Exploded View drawing on page 53 if you wish to replace grip assembly
components.
Replacing Joystick Pots
The joystick uses two pots (potentiometers) to relay its position to the software. Refer to Figure
16 and perform the steps below to replace a pot. See page 53 for an exploded-view drawing.
To test a pot
, either observe the numbers for
X
and
Y
in the
Calibrate Stick Test
screen, or
power off the game and test resistance at the pot. While moving the joystick, you should see a
steady linear increase or decrease in resistance or X and Y numbers, with no jumps.
1.
Remove the joystick from the cabinet as described above.
2.
Determine which pot to replace. The pot on the side reads the Up/Down motion. The pot on the
front reads Left/Right, as shown in Figure 16.
3.
Make a note of the orientation of the pot and mounting plate; the mounting plate is mounted with
the straight side up for the Left/Right pot, and the angled side up for the Up/Down pot. The pot
