Filtering for unintentional passages
▪
The device is designed to filter out short-term obstructions to the laser beam (passing people, birds, etc.).
Longer lasting obstructions will trigger the alarm. This function is only operational if a threshold has been selected.
The filtering zone is located between the laser and the target at two times less (
-2 x
) than the selected threshold.
Example with a 100 mm (0.33ft) threshold:
▪
A movement in the filtered zone, such as a knock against the tripod, will trigger the alarm with a longer response time
from 1 to 2 sec., due to the filter. Conversely, a movement in the threshold zone will trigger the alarm immediately.

Adjustment and maintenance of the scope, laser pointer compared to the laser range
finder
The scope is used to view the target at a distance. From a certain distance and depending on the light
levels at the time, the red dots of the laser range finder and the laser pointer are no longer seen on
the target. The target cross-hair (cross) is then the only means for targeting.
▪
Please note that the scope is adjusted in a way to make the laser range finder's red dot which appears on the target
coincide with the cross-hair at 35 m (114.8ft). Their alignment differs for distances above and below 35 m (114.8ft).
This is due to the distance between the laser and the scope mounted a few centimetres above the box.
