Image Capture Illumination
Selecting Enable Image Capture Illumination causes the decoder to flash on
every image capture. Select Disable Illumination to prevent the decoder from
using artificial illumination.
Enabling illumination usually results in superior images. The effectiveness of
the illumination decreases as the distance to the target increases.

Gain
This parameter only applies when Decoding or Image Capture Auto exposure
is disabled. Gain is a means of amplifying the raw image data before it is
converted into 256 grayscale values. Increasing the gain increases brightness
and contrast, but also increases noise (undesired electrical fluctuations in the
image) which makes the image less attractive and/or harder to decode.
To set the manual gain, scan the bar code below followed by 3 bar codes from
Appendix D, Numeric Bar Codes , in the range of 79 to 127, representing the
value. The default is 100.
