Preliminary setting of the detector optics (optional)
Preliminary setting of the detector optics must only undertaken when the signal
level was below 100 and/or the distance indication was incorrect.
 The detector line is switched on.
 The adjustment device is connected to the detector and must be set to 'Adjust'.
 The signal level is below 100 and/or the distance indication does not match the
detection distance.
1. Mount the sighting system on the detector. The mirror (1) and the front sight (2)
must be free from clearance.
2. Ensure that the two safety screws (5) are loosened.
3. Align the detector optics to the reflector using the knurled screws (3):
- knurled screw (6) for vertical setting
- knurled screw (4) for horizontal setting
- The reflector (3) and the front sight (2) must be on the axis of the circular
mark on the mirror.
4. Simultaneously check the signal level and the distance indication on the
adjustment device.
 Following successful alignment of the detector optics, the signal level must
be over 100 and the distance indication match the detection distance with
an accuracy of 10 %.
5. Remove the sighting system.
