AUDIBLE INDICATORS
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

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.
