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.

Both the color of the image and the color of the menu text can be changed. Image color
choices are black & white, red, green, and blue. Text color choices are white, green, red,
and amber.  The color green 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

Toggling button activates one of three different modes:

IR AUTO: the internal computer will measure the amount of ambient light

available, and emit a calculated amount of light to illuminate the scene as
required.  This setting will conserve battery life and is usually the preferred
setting if you have decided that the environment is so dark that you cannot
see well without its assistance.

IR MAX: the infrared emitter will output the maximum amount of infrared light

possible for maximum illumination at all times. Constant use at this setting will
minimize battery life.

IR OFF:  no infrared light is emitted.
