does not need to pass completely through the centering window.
Scan Centering On, then scan one of the following bar codes to change the top,
bottom, left, or right of the centering window. Then scan the percent you want to
shift the centering window using digits from the Programming Chart, beginning on
page 309, then Save. Default Centering = 40% for Top and Left, 60% for Bottom
and Right.
Preferred Symbology
The scanner can be programmed to specify one symbology as a higher priority over
other symbologies in situations where both bar code symbologies appear on the
same label, but the lower priority symbology cannot be disabled.
For example, you may be using the scanner in a retail setting to read U.P.C. sym-
bols, but have occasional need to read a code on a drivers license. Since some
licenses have a Code 39 symbol as well as the PDF417 symbol, you can use Pre-
ferred Symbology to specify that the PDF417 symbol be read instead of the Code
39.
Preferred Symbology classifies each symbology as high priority, low priority, or as
an unspecified type. When a low priority symbology is presented, the scanner
ignores it for a set period of time (see Preferred Symbology Time-out on page 106)
while it searches for the high priority symbology. If a high priority symbology is
located during this period, then that data is read immediately.
