Vertical Adjustment

Vertical Adjusting:

1. Adjust the vertical angle by rotating the vertical adjusting screw so that the bubble in the vertical adjusting gauge locates inside the adjusting marks.
2. Check that the beam which strikes the screen matches the specified beam pattern.
If the pattern does not match, adjust the vertical angle with the vertical adjusting screw until it does match.
3. In case they differ , turn the vertical adjusting cruise to adjust the vertical angle until the light distribution coincides with the correct lighting pattern.
