TROUBLESHOOTING
INDICATOR DESCRIPTIONS
Audible
When the MS2020 is in operation, it can provide audible feedback. These sounds
indicate the status of the scanner. 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 the Users
manual.
One Beep
When the scanner first receives power the white LED will flash, the blue LED will
turn on and the scanner will beep once ( the white LED will remain on for the
duration of the beep ). The scanner is now ready to scan.
When the scanner successfully reads a bar code, the white LED will flash and
the scanner beeps once ( if programmed to do so ). If the scanner does not beep
once and the white light does not flash, then the bar code has not been
successfully read.
Razzberry Tone
This is a failure indicator. Refer to failure modes page 19 of this manual.
Three Beeps - during operation
When placing the scanner in program mode, the white LED will flash while the
scanner simultaneously beeps three times. The white and blue LEDs will
continue to flash until the unit exits program mode. Upon exiting program mode,
the scanner will beep three times and the white LED will stop flashing.
When configured, 3 beeps can also indicate a communications timeout during
normal scanning mode.
When using one-code-programming, 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 page 19 of this manual.
