Aiming Screen

1. Use an aiming screen that meets the following specifications:
^ A height of 1.52 m (5 ft)
^ A width of 3.66 m (12 ft) (3)
^ A matte white surface
^ Shaded from ambient light
^ Properly adjusted to the floor that the vehicle rests on.
^ Moveable in order to allow parallel alignment with the rear axle of the vehicle.
^ Positioned in order to allow a horizontal line to pass an equal distance midway between the two headlamps.
2. Ensure that the screen is equipped with the following items:
^ A vertical centerline (5)
^ Two laterally adjustable vertical pieces of tape (2)
^ One vertically adjustable horizontal piece of tape (6)
3. If a standard commercial aiming screen is unavailable, use a wall that meets the following specifications:
^ A clear uninterrupted area at least 1.83 m (6 ft) high by 3.66 m (12 ft) wide
^ A surface finished with a washable, no-gloss white paint
4. After setting up and locating the aiming screen, paint or tape a reference line on the floor.
The reference line should be 7.62 m (25 ft) from the screen.
5. Park the vehicle with the front of the headlamps directly over the reference line.
