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 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 30.
Descending Tone
The scanner will emit a descending tone when the microprocessor is about to Flash upgrade.
Ascending Tone
The scanner will emit an ascending tone when the interface coprocessor is about to Flash upgrade.
Visual
Blue LED is located near the bottom corner of the vertical output
window. When the scanner is
of the LED indicates the status of the scanner and the current scan.
No Blue LED
The blue LED will not be illuminated if the scanner is not receiving
power from the host or transformer. They are also not illuminated
when all lasers are turned off.
