Install
Installation is performed in the reverse order, pay attention to the following points:
  Caution
t  Thoroughly clean the windscreen inside the retaining plate with e.g. isopropyl (technical alcohol).
t  The surface (coupling cushion) of the sensor must not get dirty or damaged when installing. A sensor with a damaged coupling cushion must be replaced.
