Barcode Scanner

The barcode scanner reads 1D barcodes,
particularly useful in a Retail Sales environment.
Point the top of

at the barcode with the
barcode printed surface parallel to
duō
. Tap the on
screen SCAN button. The laser beam will project
a red line onto the object surface, hold the scan
line still for a moment whilst over the barcode. By
default, the speaker will sound a single beep if the
read is successful. Two beeps sound if
duō
cannot
identify the barcode. Note: The Home button can
be configured to trigger the scanner.
Warning: Take care not to
scratch the scanner window as
it may affect the scanners ability to
decode the barcode.
