Reading A Bar code
1. Press the
ON/SCAN
project the scanner's bright red aiming 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.
Linear bar code
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.
