Targeting And Reading Techniques - Code Reader CR3500 User Manual

1.10 - Targeting and Reading Techniques

The CR3500 utilizes digital camera technology to take a picture of a symbol. Once an image is captured, the CR3500
utilizes advanced decoding algorithms to extract data from the captured image.
The CR3500 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 1.23).
To read a bar code with the CR3500:
1. The CR3500 features omnidirectional decoding. Center the symbol in any orientation within the targeting line
pattern (fi gure 1.24).
Note: The CR3500 can read a barcode that is not centered or aligned; however, the CR3500 performs best when a
code is aligned. If two (2) bar codes are within the imagers decode zone, the CR3500 will decode the symbol
closest to the center of the targeting line.
2. The CR3500 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 CR3500 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 CR3500 still - DO NOT SWIPE OR MOVE THE READER. Press the trigger until the CR3500 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.
