User LED Indications
Audio Sound
An audio signal (default ON) provides a quick indication if a scan passes or fails
the current test. You can change the pitch/volume of these beeps (see
Illumination Timer on page B-1). After a scan, one short, high pitch beep
indicates that the symbol passes an appropriate group of tests, while one long,
low pitch beep indicates that it fails.
