Audible Indicators

When in operation the MS2420 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, six alternate tones and no tone) plus three volume settings. To change the tone or volume, refer to the Changing the Beeper Tone and 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 35.

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 35.

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.
