Reading A Bar code
1. Press the ON/SCAN button on the 7400 or the Scan Trigger on the 7450 to project the scanner’s bright red or green aim-
ing beam. The aiming beam should be oriented in line with the bar code to achieve the quickest read. A range of 4-10
inches (10-25 cm) is recommended.
2. Center the aiming beam over the bar code. The red SCAN LED illuminates when the user presses the ON/KEY key, and
the green DECODE LED illuminates when a bar code is successfully decoded and the terminal beeps.
Omni-Directional Scanning Options
The aiming beam is smaller when the terminal is held closer to the code and larger when it is farther from the code. Symbologies
with smaller bars or elements (mil size) should be read closer to the unit. Symbologies with larger bars or elements (mil size)
should be read farther from the unit.
