illumination of the LEDs indicates the status of the current scan and the scanner.
No Red or Amber LED
The LEDs will not be illuminated if the scanner is not receiving power from the host or
transformer.

When the laser is active, the green LED is illuminated. The green LED will remain
illuminated until the laser is deactivated.
Steady Amber and Single Re d 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 or the scanner does not beep once, then the bar code
has not been successfully read.
Steady Amber and Steady Red
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 red LED will remain
on until the data can be transmitted
.

code has been scanned in this mode.

If the unit is in sleep mode, each LED will flash once every 15
seconds.
