Visual Indicators
The scanner is equipped with a red LED and green LED, which indicate the
scanner’s state and the status of the current scan respectively when the unit is in
operation.
Figure 5. LED Location
Green and Red LEDs Are Off
The LEDs will not be illuminated if the scanner is not receiving power from the
host or transformer.
Steady Green
Steady green indicates the laser is active.
Steady Green and Single Red Flash
When the scanner successfully reads a bar code, the red LED will flash and the
scanner will beep once. If the red LED does not flash and the scanner does not
beep once, the bar code has not been successfully read.
Steady Green and Steady Red
After a successful read, 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 red LED will remain on until the data can be transmitted.
Alternating Green and Red Flashes
The scanner is in configuration mode. A razzberry tone indicates an invalid bar
code has been scanned in this mode.
Steady Red
This indicated the scanner may be waiting for communication from the host.
