LEDs Trigger Cable Connector 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...

  • Page 10: Led Indicators

    1–3 LED Indicators On the back of the scanner there is a clear window through which two LEDs are visible. Green Green LED = Good Read, indicating that a bar code symbol has been scanned and decoded. LED remains on until the next scan (trigger pressed).

  • Page 11: Safety Labels

    1–4 Safety Labels The scanners use a low power visible laser diode. As with any bright light source, you should avoid staring directly into the beam. Momentary exposure to a CDRH Class II laser is not known to be harmful. The following figure shows the location of all safety labels as they appear on the scanner.
