Main dialog: System ▶ System settings ▶ Acoustic signals
You can define acoustic signals in order to direct attention to particular
events. You can define signals for the following events:
￭ Wrong manipulation
An acoustic signal will sound each time an invalid action is attempted
(e.g. pressing [
] again when Help is open).
￭ Display a message
A short beep will sound each time a message appears on the display.
This informs the user that the message must be confirmed.
￭ Button contact
Each time a button is touched on the touch screen, this will be con-
firmed by an acoustic signal.
￭ External data input
An acoustic signal will provide confirmation each time data is received
from external devices (e.g. balance, barcode reader).
