LED Power Level
This selection allows you to adjust LED and aimer brightness. Off is used when
no illumination is needed. Low is used if low illumination is sufficient. High (the
default) is the brightest setting.
Note: If you scan the Off bar code, both the aimer and illumination lights turn off,
making it impossible to scan bar codes in low light. To turn the LED
Power Level back on, move to a brightly lit area and scan either the Low
or the High bar code below.
Centering
Use Centering to narrow the imager’s field of view to make sure the imager reads
only those bar codes intended by the user. For instance, if multiple codes are
placed closely together, centering will insure that only the desired codes are
read.
In the example below, the gray area is the full imager field of view and the white
area is the centering window. Bar Code 1 will not be read, while Bar Code 2 will
be.
