Figure 24: LEDs
No Red or Amber LED
The LEDs will not be illuminated if the scanner is not receiving power from the host or transformer.
Steady Amber
When the laser is active, the amber LED is illuminated. The amber LED will remain illuminated until the laser is deactivated.
Steady Amber 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 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.
Flashing Amber then Flashing Red This indicates the scanner is in program mode. A razzberry tone indicates that an invalid bar code
has been scanned in this mode. or If the unit is in sleep mode, each LED will flash
once every 15 seconds.
Steady Red, Amber off
This indicates the scanner may be waiting for communication from the host.
