How can I change the beep sound that I hear from the computer when I scan a barcode?

Form the main screen of RTPro select File, then select Beep Settings. You can set different sound for Bad beeps and Good beeps. We have included 20 good beeps and 20 bad beeps. If you want to add a different beep, find any WAV file and copy it to \RTPro\wav\GoodBeep.wav and \RTPro\wav\BadBeep.wav
