SCANNER OPERATION
INDICATOR DESCRIPTIONS
Audible
When in operation the MS2420 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 flash then the blue LED will stay 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 31.
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 one-code-configuring, the scanner will beep three times (the current selected tone), followed by a short
pause, a high tone and a low tone. This tells the user that the single configuration bar code has successfully configured
the scanner.
Three Beeps - on power up
This is a failure indicator. Refer to failure modes on page 31.
Visual
Blue LED is located near the bottom corner of the vertical output window on the MS2420. When the scanner is
ON, the
flashing or constant, illumination of the LED indicates the status of the MS2420 and the current scan. There is an additional
amber LED next to the scale zero symbol on all MS2420 models that include a scale (see figure below).
No Blue LED
The blue LED will not be illuminated if the scanner is not
receiving power from the host or transformer. It is also not
illuminated when all lasers are turned off for any reason.
Steady Blue
When all lasers are active, the blue LED is illuminated. The
blue LED will remain illuminated until all lasers are
deactivated.
