Open the dialog System settings/Acoustic signals.
• Show a message: each time that a message appears on the screen
a short beep will be heard. This informs the user that the message
must be confirmed. This function is switched off by deactivating the
checkbox.
• Button contact (Touch Control only): each time that a button is
touched on the Touch Screen this will be confirmed by a beep. If
you touch an inactive area of the Touch Screen then no beep will be
heard.
Exit the dialog with [Home] in order to accept the settings.
If you touch or click on a fixed key which should not be used at the
moment (e. g. [START] when a determination is running) a beep will be
heard to indicate an error.
