Visual  
 
The MS5145 is equipped with a red LED and green LED that indicates the 
scanner’s state and the status of the current scan when the unit is in operation. 

 

 

 

 

Green and Red LEDs Are Off 
The LEDs will not be illuminated if the scanner is not receiving power from the 
host or transformer.  
 
Steady Green 
Indicates normal pulse or continuous laser operation.  Accompanied by a 
razzberry tone, it indicates that an invalid bar code has been scanned.

 

 

 
Flashing Green 
After a period of inactivity, the ON time of the pulsing laser will be shortened.  
During this time the green LED will flash.  This indicates that the scanner is in 
a power saver mode.  When a bar code enters the laser field, the scanner will 
wake up and return to normal pulse mode. 
 
Steady Green and Single Red Flash 
When the scanner successfully reads a bar code, the red LED will flash and 
the scanner will beep.  If the red LED does not flash and the scanner does not 
beep, then the bar code has not been successfully read.  
 
Steady Green and Steady Red 
After a successful read, 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.  
 
Steady Green and Continuous Flashing Red 
When entering the configuration mode, the red LED will flash, the green LED 
will turn on and the scanner will beep three times.  The red LED will continue to 
flash and the green LED will stay on until the unit exits the configuration mode.
