SCANNER OPERATION VISUAL INDICATORS The IS1650 has three LED indicators (yellow, white and blue) located on the top of the scanner. When the scanner is on, the flashing or constant activity of the LEDs indicates the status of the current scan and the scanner. No LEDs are Illuminated The LEDs will not illuminate if the scanner is not receiving power from the host or transformer. The scanner is in stand-by mode. Present a bar code to the scanner and the blue LED will turn on when the IR detects the object. Steady Yellow The yellow LED illuminates when the scanner is in the stand. Figure 15. Steady Blue The blue LED illuminates when the scanner is active and linear illumination is on or when the scanner is attempting to decode a barcode. Steady Blue and Single White Flash When the scanner successfully reads a bar code, it will beep once and the white LED will turn on indicating data is transmitting. If the scanner does not beep once and the white light does not turn on, then the bar code has not been read successfully. Steady White When the scanner successfully reads a bar code, it will beep once and the white LED will turn on indicating that data is transmitting. 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 Flashing of Blue and White This indicates the scanner is in configuration mode. A short razzberry tone indicates that an invalid bar code has been scanned while in this mode. Flashing Blue The blue LED will flash if the trigger is pressed while the scanner is in the in-stand presentation mode. The blue LED will stop flashing after a brief period of time. 23
