To prevent abuse like intentional speeeding, the colour ranges should be set such that
no display occurs above a specific speed. Measurements will still be stored if they are
within the defined measurement range
•
Start flashing above
Speed above which the digital display also flashes
•
Frequency on/off
Flashing on- and off-time intervals in tenths of a second
•
Activate switchgear above
Speed above which an externally controlled unit, e.g. flashing warning light, is switched
on
•
Show this in speed limit mode
Speed value to be displayed in the “Speed Limit” mode (e.g. the maximum permissible
speed)
In order to display the speed limit only above a certain speed the colour range has to
be set accordingly. For example, if the unit is supposed to display a red 50 above
speeds of 55 km/h, then the following settings are suitable:
- Measure from
3
to
198
(measure and store all)
- Green from
199
to
199
(is never displayed!)
- Red from 55
to
199
(activate red above 55 km/h)
- Display in speed-limit mode 50
(display 50)
•
Green / Red brightness range from - to
The minimum and maximum brightness limits for display of the green/red LED’s
dependent on ambient light or selection of the presets "Economic", "Normal" and
"Intense". Within these limits the DFS adapts the brightness of the display to the ambient
light, whereby 255 stands for 100% brightness. At daytime the brightness will be at
maximum and at night at minimum.
