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.
