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.
