The sound (beep) desperately needs some user options. Right now when machine beeps it does not stop after clicking "Stop" or "Cancel" and only resetting to origin will stop beeping.
The loses all information about where the error took place.

It would be really nice to be able to set the number of times a beep takes place so it could beep once or twice etc - or forever (the state of affairs currently) for users in a very noisy shop
