5.1 Reading Codes
The handheld reader reads both very small 2-D codes (e.g., QR codes) and larger 1-D codes
(e.g., barcodes). The optimum reading distance depends on the module size or minimum bar
width of the codes. The smaller this is, the closer the handheld reader should be held to the
code. In many cases, a code can be read at a distance of 10 cm.
By default, the read range is indicated by two blue bars. However, you can deactivate the dis-
play of the blue bars.
Reading Codes
The handheld reader registers itself with other devices as an input device or keyboard. Before
you read a code, start or activate the application to which the read result is to be transferred.
1.
Hold the handheld reader so that the contrast between the code and surface is as high as
possible. A reading angle between 45
° and 90 ° is optimal. The reading distance is
approximately 10 cm, depending on the code type and code size.

2.
Press the trigger button
If the reading process is successful, the function indicator on the handheld reader briefly
lights up green. When activated, an audible signal is emitted and the handheld reader
vibrates.
3.
If the code is not recognized, change the reading angle or the reading distance and press the
trigger button again.
Tip
If several codes are located right next to each other, we recommend you cover the codes that
you do not wish to read. This prevents you from inadvertently reading another code.
