Adjustable Features
The two highest gain settings may appear too noisy for many viewing environments, but can
be useful at long distances or in the very darkest environments with the use of the infrared
illuminator.
Level 8 (3rd highest gain setting):
The #8 gain setting is preferred for most very dark environments. This setting offers the
best image contrast of the high gain settings. It is most useful for viewing targets up
to 80 yards (73 meters) away.
Levels 9 & 10 (the two highest gain settings):
For
long-distance viewing , 100 to 500 yards (91 to 457 meters), the #9 and #10 gain
settings are most useful. These settings provide a brighter, albeit noisier, picture.
These two settings are also useful in the
very darkest environments with the use of
the Infrared Illuminator . The illumination provided by the IR reduces the noise that is
apparent in these high-gain images.

5. Color (control is located under the DISPLAY menu)
Both the color of the image and the color of the menu text can be changed. Image color
choices are white, red, green, and blue. Text color choices are black & white, green, red,
and amber. A green tinted display screen is typically used in night vision applications
because the rod cells in the human eye are most sensitive to the green wavelengths of
light, 550nm. You are better able to distinguish details when displayed in the color green.
The color red can be useful when you want to maintain your unassisted vision in the dark
when you look away from the viewer.
6. Brightness (control is located under the DISPLAY menu)
The display brightness has 4 settings. The default setting is 3. The darkest is 1; the
brightest is 4. As the display is a major consumer of battery power, darker brightness
settings will prolong battery life.
Access the brightness control by first choosing “display” from the menu and then choosing
the brightness option.
