Description 

OUTLINE OF RADAR ALIGNMENT PROCEDURE

WARNING: Radio waves could adversely affect electric medical equipment. Those who use a pacemaker should contact the electric medical equipment manufacturer for the possible influences before use.
CAUTION:

The system does not operate normally unless the radar alignment is performed. Always perform it.

  1. Set the target board (SST: KV99112700) to the correct position in front of the vehicle.
  2. Set the radar alignment mode ("MILLIWAVE RADAR ADJUST" on "Work support") with CONSULT, and then perform the adjustment according to the display. (Distance sensor automatically adjusts.)

CAUTIONARY POINT FOR RADAR ALIGNMENT PROCEDURE

CAUTION:
  • For radar alignment procedure, choose a level location with a few meter of working space in front and surrounding the vehicle.
  • Vehicle must be stationary and unoccupied during the whole alignment procedure.
  • Any slight vibration during the alignment procedure can cause the test to fail. If this happens, you will have to restart the alignment process.
  • The ignition switch must be in the ON position.
  • The battery voltage must not fall below 12 volts during the whole alignment procedure. Failure to maintain adequate battery voltage will cause the test to fail. If this happens, you will have to restart the alignment process.
  • The target board must be set in front of the vehicle facing the sensor.
  • Adjust the radar alignment with CONSULT. (The radar alignment procedure cannot be adjusted without CONSULT.)
  • Never enter the vehicle during radar alignment.
  • Never block the area between the radar and the target board at any time during the alignment process.
  • Accurate steering wheel setting is crucial. Once set, do not disturb the steering wheel for the remainder of the alignment procedure.
  • For proper system operation and adjustment, all vehicle wheels must be of the same size.
