The scanning sequence is defined by the user’s application. A typical sequence is:
Point the mobile computer at the barcode and press the Trigger key
.
Point the LED lightbeam at barcode as shown in the scan position illustration above.
The scanner reads the barcode and the results are indicated.
A “Good Read” means that the scanner has effectively recognized and decoded the bar code.
In most cases, the application program provides an indicator signal to indicate a good read.
If the read is incorrect, try again paying close attention to the instructions.
When reading a small bar code, decrease the distance between the mobile computer and the
bar code. For larger bar codes, position the mobile computer so that the bar code fits into the
LED light beam. When reading a very high density bar code, decrease the distance between
the mobile computer and the bar code. For a low density bar code, increase the distance
between the mobile computer and the bar code.
