Green, Red & Yellow LEDs are off
The LEDs will not be illuminated if the scanner is not receiving power from the host or transformer.

Steady Yellow
The CodeGate button is not active. If a bar code is in the scan field, the laser will turn on. The bar code will be decoded and transmitted to the host automatically.
Steady Green
When the laser is active, the green LED is illuminated. The green LED will remain illuminated until the laser is deactivated.
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 or the scanner does not beep once, then the bar code has not been successfully read.
Steady Green 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.
