How Do I Use It?
Section
control
These speed cameras work in pairs, and do not
measure your current speed but your average
speed between the two speed cameras. Both
identify your car and record the exact time you
pass them. They use the difference between
the two points in time to calculate your average
speed.
TRAX325 warns you when you approach one of
these speed cameras, but as you pass by, the
warning stays on, and your
average speed is measured until you reach
another speed camera of this type. If your
average speed exceeds the speed limit between
the two speed cameras, you receive the same
special warning sound as with the other speed
camera types.
In the rare case TRAX325 cannot register the
moment you pass the second speed camera (for
example, it is placed at the exit of a tunnel where
GPS position is not yet available) the warning
continues. Just tap the speed camera symbol
displayed on the screen to stop the warning.
Red
light
These cameras check if you obey traffic lights.
The warning is similar to mobile speed cameras:
as there is no speed limit given, only the proximity
is announced.
Camera directions
A speed camera can measure the speed of one direction of the traffic,
both directions, or even several directions in an intersection, when they
are mounted on a rotating base. The same directions apply to red light
cameras. TRAX325 warns you only if you drive in a measured or possibly
measured direction. The measured direction of the camera appears with
the following symbols:
