HS-51/HS-51X Wireless Handheld Reader User Manual 3-3
Basic Operations
Dual Optics
The reader’s dual field optical system can read small 2D symbols as well as larger 1D
symbols. An image is captured from each field. The decoder first operates on the image
(High Density or Wide Angle) which was successfully decoded on the last cycle. If unsuccessful,
the next image is decoded.
Move the reader closer to decode smaller symbols and farther away to decode larger symbols.
Imaging Area
The reader’s
optics are divided into High Density and Wide Angle decode zones. Each
decode zone is 960 x 640 pixels.
