SCANNER OPERATION
INDICATOR DESCRIPTIONS
Audible
When in operation, the MS2421/MS2422 scanner provides audible feedback that indicates the status of the unit and the current scan. Eight settings are available for the tone of the beep (normal, 6 alternate tones and no tone) plus three volume settings. To change the tone or volume, refer to the Changing the Beeper Tone & Volume section of this manual.
One Beep
When the scanner first receives power, the blue LED will turn on and the scanner will beep once. The scanner is now ready to scan.
When the scanner successfully reads a bar code, the blue LED will flash and the scanner beeps once (if configured to do so). If the scanner does not beep once and the blue light does not flash, then the bar code has not been successfully read.
Razzberry Tone
This is a failure indicator. Refer to failure modes on page 30.
Three Beeps - during operation
When placing the scanner in configuration mode, the blue LED will flash while the scanner simultaneously beeps three times. The blue LED will continue to flash until the unit exits configuration mode. Upon exiting configuration mode, the scanner will beep three times and the blue LED will stop flashing.
When configured, three beeps can also indicate a communications timeout during normal scanning mode.
When using
