Setting The Distance Sensor Target Board: Description

Accurate adjustment of the radar alignment requires that the distance sensor target board be accurately positioned.

CAUTION: If the radar alignment is adjusted with the distance sensor target board in the incorrect position, the distance system will not function properly or the alignment procedure may not be completed successfully.

DISTANCE SENSOR TARGET BOARD FINAL SETTING
1. With the distance sensor target board arm extended, the laser beam (1) emitted by the laser assembly (A) will be reflected back (B) toward the laser assembly.
  NOTE: When adjusted properly, reflected laser beam (B) must align with emitted laser beam (A) and the two laser beams will be seen as one.
2. Rotate the distance sensor target board to achieve the necessary horizontal adjustment.
3. Adjust the distance sensor target board leveling screws to achieve the necessary vertical adjustment.
