General Information

- If you use a screen, the screen should be at least 1.52 m (5 ft) high x 3.66 m (12 ft) wide with a matte white finish, well shaded from extraneous light.
- Properly adjust the screen to the floor on which the vehicle rests.
- The screen should be moveable so that you can align the screen parallel to the rear axle of the vehicle.
- Position the screen so that a horizontal line drawn perpendicular to the centerline of the screen will pass an equal distance midway between the two headlamps.
- The screen should have the following items:
- A vertical centerline (4)
- Two laterally adjustable vertical tapes (2)
- One vertically adjustable horizontal tape (3)
- If a regular commercial aiming screen is not available, the screen may consist of a wall having a clear, uninterrupted area at least 1.83 m (6 ft) x 3.66 m (12 ft) wide. The surface should be finished with a no-gloss white paint.
- After the aiming screen has been set up and located, paint or tape a reference line (6) on the floor 7.62 m (25 ft) from the screen. Park the vehicle with the front of the headlamps directly over this reference line.
