Reading Symbols with the HE40T
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 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.
Hold the HE40T Reader still - DO NOT SWIPE OR MOVE
THE READER. Press the trigger until the HE40T beeps,
indicating the bar code has been successfully decoded.
A programming code symbol encodes special messages used to
program the HE40T.
