5.1.2 Portrait orientation
The V9 vario unit is an indicator only and has no controls. Information displayed
is controlled by the main display unit.
The V80 vario unit is having three buttons to toggle between screens. More
information is given in chapter 6.1.12.4
5.1.3 Buttons
All buttons have a dynamic function; the first time one presses each button, it displays its
function without executing any action. Not all buttons have a function on every page. In
some cases buttons have a long press function.
5.1.3.1 Power Button
The power button is marked with the ON/OFF symbol. It has multiple functions. Primarily it
is used to switch the system on and off.
5.1.4 Rotary Switches (Knobs)
The main display unit has four rotary knobs. Each has a single function with the exception
of the zoom knob which has, in some cases, a function other than zoom. With the upper-
left rotary knob the volume can be adjusted. The upper-right rotary switch is the mode
selector (it changes the mode of the operation). At the lower-right is the up/down knob
which is used for selecting sub-pages, sub-menus and editing menus. At the lower-left is
the zoom knob which is multifunctional. While its main function is to change the zoom level
within graphic mode, it can also be used if an error is made during editing; it is possible to
move the cursor back by rotating this knob. However this can only be done if 'editing' is
active which is shown by the cursor blinking.
