Note: The HE40T can read a symbol that is not centered; however, the
HE40T performs best when a code is centered.
The HE40T features omnidirectional decoding. Aiming the targeting laser at
the center of the symbol ensures the best performance for decoding. The
HE40T can read a symbol that is not centered and, under certain
circumstances if multiple symbols are within the field of view, the user must
take care of which symbol is read. The decoder will start from the center, but
if the center symbol is not decodable, it may decode another symbol, if
multiple symbols are present within the field of view.
2.
The HE40T was developed to decode both very small 2-D symbols and
larger 1-D symbols. The reader features two imagers to create an innovative
dual decode zone. The HE40T features a high speed processor and decodes
both zones simultaneously, by default. The reader has one imager focused on
a near-field for smaller codes (optimal focal point is 4 inches) and one
imager focused on a far-field for larger codes (optimal focal point 9 inches).
To read smaller symbols, move the HE40T closer to the symbol. To read
larger symbols, move the reader farther away from the symbol. The entire
HE40T decode zone varies between two (2”) and twenty (20+”) or more
inches.
3.
Hold the HE40T still - DO NOT SWIPE OR MOVE THE READER. Press
the trigger until the HE40T beeps, indicating the code has been successfully
decoded.
4.
To read a symbol with a shiny background, hold the HE40T slightly tilted to
avoid the reflected light from the LEDs.
5.
The reader may be optimized to your specific environment by scanning
codes in Chapter 6, “Advanced Decoder Performance”.
