Visual Indicators
  
 
There are four LEDs located on the top of the IS3480.  When the scanner is on, 
the flashing or constant illumination of the LEDs indicates the status of the 
current scan and the scanner. 
 
 
No LEDs 
 
The LEDs will not be illuminated if the scanner is not receiving power from 
the host or transformer.  They are also not illuminated when all lasers are 
turned off for any reason. 
 
Steady Blue 
 
When the laser is active, the blue LED is illuminated.  The blue LED will 
remain illuminated until the laser is deactivated.  
 
Steady Blue and Single White Flash 
 
When the scanner successfully reads a bar code, the white LED will flash 
and the scanner will beep once.  If the white LED does not flash or the 
scanner does not beep once, then the bar code has not been successfully 
read. 
 
Steady White and Blue 
 
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 Blue and White Flashes 
 
This indicates the scanner is in program mode.  A razzberry tone indicates 
that an invalid bar code has been scanned in this mode.  
 
Steady White, Blue Off 
 
This indicates the scanner may be waiting for communication from the host.
