NUC Type

The non-uniformity correction (NUC) of the signal is a complex electronic process, which
requires a uniform temperature body in front of the detector or the objective lens.
For the convenience of the user, the device has a built-in motorized mechanism for per-
forming NUC procedure by automatically dropping a miniature shutter plate in front
of the detector. This process takes less than a second and is accompanied by acoustic
noise resembling a click.
Selecting the NUC type changes the NUC mode be-
tween Internal and External.
In situations requiring maximum suppression of the
external noise, the device can operate in External
shutter mode, which isolates the operation of the
motorized mechanism.
When the External shutter mode is activated, the
motorized mechanism of the shutter is blocked, Auto
NUC function is deactivated.
In that case the mechanism will be performed by the user, who must cover the objec-
tive lens, before pressing . In order to cover the objective lens use the hand or the
protective cap, otherwise the image of the display will resemble the negative effect of
the observed scene.
Upon power on, the device automatically performs two consecutive NUC-cycles. Dur-
ing this period of time it is desirable to cover the objective lens with the protective cap
or with the hand. These actions are necessary only when the External shutter mode
is activated.

When Standby function is on, the device will be
powered on every time, when the tilt angle is less
than 45° to both sides (fig. 1) and 60° upwards
and downwards (fig. 2). As soon as these condi-
tions are not fulfilled, the device will automati-
cally switch to standby mode.

Alignment

With Alignment functionyou can precisely align
the optial axises of the day sight and the clip-on
atachment. The manufacturing process of the
device ensures the shooting precision tolerance
within 3 to 5 cm at 100 m. By this Alignment
function you can achieve much better results in
the accuracy.
Alignment is made electronically by pressing the
the menu Settings > Alignment > Left/Right, Up/Down (in clip-on mode only). In posi-
tion X: 0, Y: 0 the image is in center of the screen of the device. By using the alignment
functionuser moves the image in all directions.
If the impact point is left of the target, the image should be moved to the right, increas-
ing the value of X, and vice versa.
The adjustment is limited to 10 steps in each direction. Each step corresponds to ap-
prox. 3 cm at 100 m. If the need for alignment exceeds the limit of 3 steps, please
contact your vendor.
