Reading Symbols with the HE40T

1. The HE40T features omnidirectional decoding. Center the

symbol in any orientation within the laser dot aiming pattern,

as shown in Figure 1–25.

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 unit 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 unit 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 unit farther away

from the symbol. The entire HE40T decode zone varies

between two (2”) and twenty (20+”) or more inches.
