6.2. Using the Aiming Guide to Scan
1. To scan a barcode within an aiming range:
• Make sure that two central LED light patterns overlap each other on the chart.
• Locate the center of the overlapped LED light pattern on the center of the
barcode to scan.
2. To scan a barcode wider than an aiming range:
• Aim the barcode from farther away.
• Make sure that the barcode is between two LED light patterns at right and left
ends.
Note: Due to specular reflection (mirror-like reflection of light), scanning performance
may differ depending on the media on which the target barcode is printed. Angle the
scanner to about 15 degrees if you have difficulties in scanning due to specular
reflection.
