3.1 General principles

The dialogue boxes are displayed at the bottom of the screen. They do not overlap the space set aside for the curves,
and so leave an unobstructed view of the user's action on the channel. Only the adjustments that concern this curve
remain displayed. However, in some rare cases, a virtual keypad must be used: this keypad appears in the centre of the
screen and so covers the space of the curves.

The dialogue box opened is erased by clicking the button at top right in the dialogue window.

A change made to a parameter of a dialogue window takes effect immediately and modifies the curves, with no prior
confirmation.

The multilingual online help (common to all modes) can be accessed using the icon of the screen. It explains the
keys of the keypad: pressing any key of the keypad displays the help menu of the key pressed, without starting the
function associated with the key. The name and icon of the key are displayed above the explanation.
To exit from the online help function, point the stylus to the help window.
