SCANNER OPERATION 
Indicators 
Visual 
The MS9535 has three LED indicators (blue, white and amber) located on the 
head of the scanner.  When the scanner is in operation, the flashing or stationary 
activity of the LEDs indicates the status of the scanner and the current scan. 
Blue, White & Amber LEDs are off 
The scanner is not receiving power from the cradle or the scanner’s 
internal battery. 
The scanner is in full sleep mode.  Press the CodeGate button to 
wake the scanner from full sleep mode.  The blue LED will start to 
flash as the unit exits full sleep mode. 
Steady Amber  
After establishing communication, when the scanner is put into the 
cradle and the battery has been fully charged, the amber LED will 
remain steady.  
If the communication is not established, when the scanner is put into 
the cradle, the amber LED will stay on after a short delay. 
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, the blue LED remains steady and the scanner will beep once.  
If the scanner reads the bar code successfully at a relatively long 
distance but still within the 10-meter operation range, the white LED 
may flash after a short delay. 
Steady Blue and Steady White 
After a successful scan, the scanner transmits the data to the cradle. 
If the cradle is not ready to accept the information, the scanner’s 
white LED will remain on until the data can be transmitted or until a 
communication time-out occurs.
