The scanner provides sounds to signal certain conditions.  To change the 
volume (four settings are available) or turn the beeper off, refer to Beeper Tones 
in the Programming Guide. 
 
One Beep 

When the scanner first receives power, the red LED will 
flash, followed by the green LED, and then the scanner 
will beep once.  After the scanner performs this start-up 
sequence, the scanner is ready to scan.

 

 

 

When the scanner successfully reads a bar code, the 
green light will flash and the unit will beep once.  If the 
green LED does not flash or the scanner does not beep, 
then the bar code read is not successful. 

 
 
 
Razzberry Tone 

If, upon power up, the scanner emits a razzberry tone the 
scanner has failed diagnostics.  

 
 

The scanner can be programmed to emit a 
razzberry tone when the timeout occurs during 
communication between the host and scanner.  
Refer to Audible Indicators for Communication 
Timeouts the Programming Guide. 

 
 
 
Three Beeps 

When entering program mode, the green LED will flash 
three times while the scanner simultaneously beeps 
three times.  When exiting program mode, the same 
visual and audible indications will occur. After this 
sequence is completed, the red LED will turn off. 

 
 

The scanner can be programmed to emit three 
beeps when the timeout occurs during 
communication between the host and scanner.  
Refer to Audible Indicators for Communication 
Timeouts the Programming Guide.
