How to Scan
Figure 2 illustrates some tips to help get the best scanning results:
1.
The scanner must be pointed at a slight angle to the bar code.
Do not hold the scanner perpendicular to the bar code.
2.
The laser beam must cross the entire bar code. The scanner cannot correctly read if the entire bar code is not scanned.

Scanning Range
There are currently four different model types for this scanner.
Depending upon the model type of your scanner, you’ll need to hold the unit at a given distance from the bar code to achieve optimum scanning results. The following diagrams provide range of field information for each of the models when scanning grade A, Code 39 bar codes: Standard Range (SR), High Density (HD), Long Range (LR) and Extra Long Range (XLR).
NOTE
In the context of the illustration below, a "mil" represents the minimum bar code element width. Measurements are based on SR models set with the standard 28° scan width (as opposed to the Half
Angle setting of 14°). Reference the PowerScan Programming Manual for more information about the
Half Angle feature.
Specifications are subject to change without notice.

Active Symbologies
The active (enabled) bar code symbologies in the factory defaults are:
• Code 39 (C39)
• Code 128 (C128)
• Interleaved 2 of 5 (I 2 of 5)
Your scanner should be pre-programmed with these standard factory default settings, unless...
...it was shipped to you programmed with unique, customer configuration settings.
...you or another user have made changes to scanner programming.
