Scanner Features

The scanners use a low power visible (red) laser diode for scanning. The

trigger turns on the laser which scans a label at approximately 36 scans

per second.

Trigger

Cable Connector

LEDs

The laser beam:

-exits through the scan window

-reflects off the label back through the window

-is detected by a sensor in the scanner

When a label is read, the laser beam is automatically turned off until the

trigger is pressed again. If no label is read, the laser beam automatically

turns off after approximately 3 seconds and remains off until the trigger

is released and pressed again.

Note: The Extended Range Scanner (Catalog No. 2755-HUG-9) has a

two position trigger. The first detent provides a spotter beam and the

second position provides a scan line.

LED Indicators

On the back of the scanner there is a clear window through which two

LEDs are visible.

Green Red

Green LED = Good Read, indicating that a bar code symbol has been

scanned and decoded. LED remains on until the next scan

(trigger pressed).

Red LED = Scanning, indicating that the laser light is on.
