VORAD VS 400 system Improper alignment can cause the system to improperly detect objects in the vehicle s path Every precaution should be taken to ensure the VS 400 system alignment both horizontal and vertical is correct Alignment of the Forward Looking Radar is a repetitive process of adjusting the vertical and horizontal axis using the bracket screws The vertical alignment must be completed with a digital level The horizontal alignment is started by referencing the FLR against fixed positions on the bumper and using a digital level The horizontal alignment is completed by performing a calibration procedure with the Service Ranger 3 diagnostic software while driving the unit equipped with the VORAD system Note The vehicle must be parked on a level surface If the vehicle is on an angled surface then level compensations must be made to ensure proper alignment Below are steps for a typical alignment procedure Other companies such as Hunter Engineering Company 11250 Hunter Drive Bridgeton MO 63044 314 731 3020 can also be contacted to establish alignment using other professional alignment equipment 2 Vertical Alignment The steps for vertical alignment are as follows 1 Hold a digital level against the flat surface of the mounting bracket 2 Use a 5 32 Allen wrench to loosen the locking screws Note Failure to loosen both locking screws will result in damage to the alignment bracket 3 Adjust the alignment screws until th
