The CR2 utilizes digital camera technology to take a picture of a symbol. Once an image is
captured, the CR2 utilizes advanced decoding algorithms to extract data from the captured
image.
The CR2 is available as a palm-held unit or users may purchase a clip-on “gun format” handle.
The palm held unit features left and right buttons (gure 1.1). These buttons may be
programmed to perform various features (see section 4.8). The reader is shipped with the left
button and right button functioning as a decode symbol command.
The “gun format” handle features a trigger on the handle (gure 1.2). The two triggers on the top
of the unit also work when the handle is attached.
To read a symbol with the CR2:
1. The CR2 features omnidirectional decoding. Center the symbol in any orientation within
the laser dot aiming pattern (gure 1.3).
Note: The CR2 can read a symbol that is not centered however, the CR2 performs best
when a code is centered. If two (2) bar codes are with the imagers decode zone, the CR2
will decode the symbol closest to the center of the aiming dot.
