Targeting And Reading Techniques - Code Reader 2500 User Manual

1.9 - Targeting and Reading Techniques

The CR2500 utilizes digital camera technology to take a picture of a symbol. Once an image is captured, the CR2500
utilizes advanced decoding algorithms to extract data from the captured image.
The CR2500 is available as a palm-held reader or users may purchase a handle (available in various types).
The palm held reader features left and right triggers. These triggers may be programmed to perform various features. The
reader is shipped with the left trigger and right trigger functioning as a decode symbol command.
Each handle has a trigger on the grip. The two triggers on the top of the reader also work when the handle is attached
Figure 1.24).
To read a bar code with the CR2500:
1. The CR2500 features omnidirectional decoding. Center the symbol in any orientation within the targeting line
pattern (fi gure 1.25).
Note: The CR2500 can read a bar code that is not centered or aligned; however, the CR2500 performs best
when a code is aligned. If two (2) bar codes are within the imagers decode zone, the CR2500 will decode the
symbol closest to the center of the targeting line.
2. The CR2500 was developed to decode both very small 2-dimensional symbols and larger 1-dimensional
symbols. The reader has an innovative dual fi eld decode zone. The CR2500 DECODES ONLY THE WIDE
FIELD BY DEFAULT. By default, the reader will focus on wide fi eld for larger codes (optimal focal point 3.3
inches). The reader can be programmed to focus on high density for smaller codes (optimal focal point is 3.3
inches).
3. Hold the CR2500 still - DO NOT SWIPE OR MOVE THE READER. Press the trigger until the CR2500 beeps,
indicating the code has been successfully decoded.
4. The reader may be optimized to your specifi c environment by scanning codes in Chapter 2.
