Targeting and Reading Techniques

Getting Started

Rev 2.0.0, Jan 2009 HawkEye™ 45T User Manual 1-35

To read a symbol with the HE45T:

1. The HE45T features omnidirectional decoding. Center the symbol in any

orientation within the laser dot aiming pattern (Figure 1–38).

Note: The HE45T can read a symbol that is not centered; however, the

HE45T performs best when a code is centered.

The HE45T features omnidirectional decoding. Aiming the targeting laser at

the center of the symbol ensures the best performance for decoding. The

HE45T 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 HE45T was developed to decode both very small 2-D symbols and

larger 1-D symbols. The reader has an innovative dual field decode zone.

The HE45T DECODES BOTH ZONES SIMULTANEOUSLY. The reader

has a lens focused on a near-field for smaller codes (optimal focal point is 4

inches) and one lens focused on a far-field for larger codes (optimal focal

point 9 inches). To read smaller symbols move the HE45T closer to the

symbol. To read larger symbols move the reader farther away from the

symbol. The entire HE45T decode zone varies between two (2”) and twenty

(20+”) or more inches.

3. Hold the HE45T still - DO NOT SWIPE OR MOVE THE READER. Press

the trigger until the HE45T beeps, indicating the code has been successfully

decoded.

4. To read a symbol with a shiny background, hold the HE45T slightly tilted to

avoid the reflected light from the LEDs.
