Indicators

Light, reflected off the bar code symbols, passes back
through the window and is detected by light sensors.
When a label is read, the laser is automatically turned
off until the next pull of the trigger.
The laser beam looks like a narrow red line of light. It
is actually a tiny spot of light traveling very fast. The
laser spot moves across the bar code symbol at
approximately 35 scans/second. The bar code is
scanned many times in a short period of time.
The rear of the scanner has two indicators that
provide a visual indication of scanner operation.
Table 3.A defines the color and function of each
LED indicator.
