Gain

Parameter # F4h, F0h, A7h
This parameter only applies when Decoding or Image Capture Autoexposure 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
the range of 79 to 127, representing the value.
