Q1
Tips:
If you have pressed the rightward arrow key too often and went too far
down in the menu selection list, move upwards again by pressing the
leftward arrow key.
If you want to quit an invoked menu selection window without having made
a selection, just press the Menu key as often, until the menu window is
closed.
The selection of some menu items invokes a dialog. These dialogs are displays
in which values can be modified. However, only a few values can be modified
via the operator panel.
In such input dialogs you move from one parameter to another by using the
arrow keys. If a parameter must not be changed (for instance, because it is a
parameter that is subject to the calibration lock, which is closed at that moment),
it will be crossed out in the display.
If you have selected a parameter that can be changed, you may switch into the
edit mode via the Enter key.
In order to render the operation more comfortable, there are different methods of
defining a new value, depending on the type of the value to be changed:
Direct entry of a new numerical value
If you would like to replace individual characters only, delete the characters step
by step from the right using the leftward arrow key. Then enter the new
characters via the numerical keys including decimal point and minus sign.
If it is easier to replace the entire value by a new one, just start with your entry
right away: As soon as you press any numerical key the preset value will be
deleted and overwritten by the new entry.
Quit the edit mode via the Enter key. This initiates a test for consistency: If you
have entered a value that does not make sense in the present context or is not
permissible, you will not be able to quit the edit mode. This way, the user is
forced to correct the value he has entered.
