1.3 Positioning and reading techniques
This handheld uses digital camera technology to record an image of the code to be read. After
an image has been recorded, the handheld uses highly developed evaluation procedures to
evaluate the data contained in the recording.
This handheld supports you with target projections in the form of two squares distinguished by
color when codes are sighted and focused. This projection is realized by one red and one
green LED on the handheld. Precise positioning becomes increasingly important in the case of
small codes or codes with a high information density.
Sighting and reading 1D and 2D codes
1. With the trigger button pressed, aim the red square at the code to be read.
2. Alter the distance between the handheld and the code, depending on the position of the
green square: the code is optimally sighted as soon as the two squares overlap.
The code is read automatically. In the event of successful decoding, the acoustic and
tactile signal sounds and the status LED flashes green once (depending on the
configuration of the handheld).

1.4 Optimizing reading performance
With this handheld, you can improve the reading performance by specifying the size and
information density of the codes that are to be scanned.
1. If you typically tend to read a wide variety of codes, scan the Wide-Field DOT (Default)
code.
2. If you typically tend to read small, 2D codes with high information density, scan the SXGA
Mode code.
3. If you typically tend to read medium-sized, 1D and 2D codes with low information density,
scan the VGA Mode code.
4. To save your settings, scan the Save Settings code.
