(6) Where the DFS 700 is mounted in a fixed position above the road (e.g. on a signal
bridge), the DFS 700 must be located at a height of 4 to 6 metres centrally above the
lane to be monitored. The fixing pole holding the DFS 700 must be vertically tiltable, so
as to align the DFS 700 to the lane.
Tilt the DFS 700 vetically such that the radiated beam lies over the carriageway to be
monitored, see Figure 7-3. The vertical angle of tilt should be 6° to 8° downwards.
