The scanner has blue and white LED 
indicators on either side of the button on the 
top of the unit.  When the scanner is on, the 
intensity of the LED and the flashing or 
stationary activity of the LEDs, indicates the 
status of the current scan and the diagnostic 
scanner. 
 
 

The LEDs will not be illuminated 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 switch to a high intensity blue when the IR detects the object. 

 

The high intensity blue LED is illuminated when the scanner is active and 
attempting to decode a bar code. 

 

When the scanner successfully reads a bar code the unit will beep once and 
the white LED will flash once indicating data has been transmitted 
successfully. The blue LED will return to the low intensity state if no other 
objects are presented in the active scan area. 

 

If the scanner does not beep once and the white light does not flash, then the 
bar code has not been successfully read. 
 

When the scanner successfully reads a bar code, it will beep once and the 
white LED will turn on indicating data is being transmitted. 

 

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.  

 

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.
