Visual Indicators
The 7120 is equipped with a blue and a white LED that indicates the scanner's
state and the status of the current scan when the unit is in operation.
No LEDs
The LEDs will not be illuminated if the scanner is not receiving power from the
host or transformer.
Steady Blue
When the laser is active, the blue LED is illuminated. The blue LED will remain
on until the laser is deactivated.
During the power save mode, the laser will turn on and off. During this period,
the blue LED will remain on.
Steady Blue and Single White Flash
When the scanner successfully reads a bar code, the white LED will flash and
the scanner will beep once. If the white LED does not flash or the scanner
does not beep once, then the bar code has not been successfully read.
Steady White and Blue
After a successful scan, the scanner transmits the data to the host device.
Some communication modes require that the host inform the scanner when
data is ready to be received. If the host is not ready to accept the information,
the scanner's white LED will remain on until the data can be transmitted.
Alternating (Toggling) Blue and White
This indicates the scanner is in configuration mode. A razzberry tone indicates
that an invalid bar code has been scanned in this mode.
