When the IS6520/MS6520 scanner is in operation, it provides 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). To change the
tone, refer to the MetroSelect Configuration Guide (MLPN 00-02407).
When the scanner first receives power, the green LED will
turn on, then the red LED will flash and the scanner will
beep once. (The red LED will remain on for the duration of
the beep.) The scanner is ready to scan.
When the scanner successfully reads a bar code, the red
LED will flash and the scanner beeps once (if programmed
to do so). If the scanner does not beep once and the red
light does not flash, then the bar code has not been
This tone is a failure indicator. Refer to “Failure
Modes" page 10.
Three Beeps - During Operation
During operation of the scanner, the red LED will flash
while the scanner simultaneously beeps three times (while
going into programming mode).
The red LED will continue to flash until the unit exits
program mode. Upon exiting program mode, the scanner
will beep three times and the red 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 then by a high tone and a low tone. This tells the
user that the single configuration bar code has successfully
configured the scanner.
