DOCTER DOCTER®sight III - Manual (Page 16)

Brightness Control of Light Dot
Using an integrated control electronics, the different lighting conditions in the practical
use are considered. The light dot intensity is automatically adapted according to the
environmental brightness in target direction. The measurement is analog to the
sensitivity of the human eye. When the sensor at the front side of the sight is
covered, a visible brightness reduction of the light dot occurs. Therefore, the sensor
must not be covered by gun parts.
In addition to the automatic dot brightness adaptation to the light conditions in target
direction, an individual adaptation can be made by means of choosing from three
different operating modes (characteristic curves). Immediately after taking off the
programming cap, the currently chosen operating mode is shown by means of the
additional MODE LED (5) at the top of the DOCTERsight. To avoid disturbing effects
due to this display, the LED is visible only when you nearly vertically look from above
onto the DOCTERsight III. Please consider that this display is also adapted to the
environmental brightness to have a good visibility on the day as well as to prevent a
dazzling effect in the night.
The characteristic curves are assigned to preferred application purposes:
Number of
flashes
MODE Features Preferred use
1 Minimal Curve with lowest energy
consumption
Long-term and other
special application
2 Dynamic Standard curve with balanced
features
Universal
3 Power Increased basic brightness and
high maximum brightness
