Major 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.

Reflected Light
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 0.5 to 3 seconds (timeout is adjustable)
and remains off until the trigger is released and pressed again.
