A selection indicator shows the current position within the menu

Circular movement
Move one finger clockwise over the Touch-Wheel to move the
selection indicator downwards or to the right in the list, depend-
ing on how the menu items are arranged. Circling anti-clockwise
moves the selection indicator to the left or upwards in the list.
Alongside navigation within the menu structure, the Touch-Wheel
is also used to set parameters. Increase the values with a clockwise
motion. Reduce the values with an anti-clockwise motion.
4.1.3 Keys
Note
Tap on the keys only briefly to trigger the required action.
If a key is touched for too long, the programming unit
will not respond.
"MENU" key
The MENU key has two functions:
- From the start screen, tap on the MENU key to navigate to the
first of 5 menu structure levels.
- Tapping the MENU key while in the menu structure will re-
turn you to the previous menu level.
"OK" key
The OK key has four functions:
- On the start screen, tapping the OK key will activate the
required operating mode previously selected with the Touch-
Wheel (see "Selecting operating modes").
- Within the menu structure, tapping the OK key confirms the
selected menu item and takes you to the next menu level
down.
- At the parameter level, tapping the OK key saves the current-
ly set parameter.
- At every menu level, you will see the entry BACK. Selecting
BACK takes you to the next higher menu level.
If there is no user action for over 5 minutes (no circular motion and
neither MENU nor OK tapped), the programming unit display auto-
matically jumps back from the menu structure to the start screen.
Parameter changes made before this which had not yet been con-
firmed with OK are lost. The parameters retain the values previ-
ously saved.
4.1.4 Contractor access
Note
Some menu items are protected by a code and can only
be accessed and adjusted by a qualified contractor.
