Single Line Mode (DLL2021 only)
The single line option allows temporarily switching from full scan pattern
to a single scan line preventing the wrong barcode to be read. This
feature is especially helpful on sheets or products where multiple
barcodes are printed.
To use this option proceed as follows:
1. Press the button on top of the scanner to switch from the full scan
pattern to a single scan line;
2. Aim the single scan line on the barcode to be scanned while holding
the button;
3. Make the line to completely cross the barcode, then release the
button. A beep indicates the barcode has been accepted by the
scanner;
4. After successful reading the single line blinks. During the scan line
blinking, the scanner will not read a barcode. After one second, the
scanner will return to normal mode. If pressing the trigger during the
scan line blinking, the single line procedure will start again.
