Audible Indicators
When the fusion scanner 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,
six alternate tones, and no tone). For instructions to change the tone of the beeper, refer to the
"MetroSelect Configuration Guide (00-02407)".
One Beep
When the scanner first receives power, the white LED will flash, one blue LED will turn on
and the scanner will emit a beep (the white LED will remain on for the entire duration of the
beep). The scanner is now ready to scan.
When the scanner successfully reads a barcode, the white LED will flash and the scanner will
emit one beep (if configured to do so). If the scanner does not emit one beep and the white
light does not flash, it indicates that the barcode has not been successfully read.
Razzberry Tone
This is a failure indicator. Refer to
Three Beeps - during operation
When you place the scanner in configuration mode, the white and blue LEDs flash when the
scanner emits three beeps. The white and blue LEDs continue to flash until the unit exits the
configuration mode. When the scanner exits the configuration mode, it will emit three beeps
and the white LED will stop flashing.
When configured, three beeps can also indicate a communications timeout during normal
scanning mode.
When you use one-code-programming, the scanner emits three beeps; the current selected
tone, followed by a short pause, then a high tone and a low tone. This indicates that the single
code configuration has successfully configured the scanner.
Three Beeps - on power up
