1.10 - Targeng and Reading Techniques

The CR3500 ulizes digital camera technology to take a picture of a symbol. Once an image is captured, the CR3500 ulizes 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 le and right triggers. These triggers may be programmed to perform various features. The reader is

shipped with the le trigger and right trigger funconing 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 aached (Figure 1.23).

To read a bar code with the CR3500:

1. The CR3500 features omnidireconal decoding. Center the symbol in any orientaon within the targeng line

paern (gure 1.24).

Note: The CR3500 can read a bar code 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 targeng line.

2. The CR3500 was developed to decode both very small 2-dimensional symbols and larger 1-dimensional symbols.

The reader has an innovave dual eld decode zone. The CR3500 DECODES ONLY THE WIDE FIELD BY

DEFAULT. By default, the reader will focus on wide eld for larger codes (opmal focal point 3.3 inches). The

reader can be programmed to focus on high density for smaller codes (opmal focal point is 3.3 inches).

3. Hold the CR3500 sll - DO NOT SWIPE OR MOVE THE READER. Press the trigger unl the CR3500 beeps,

indicang the code has been successfully decoded.

4. The reader may be opmized to your specic environment by scanning codes in Chapter 2.
