Navigation in the menu
There are basically two ways of navigating in both menus:
● Press and release the shift key (≤ 500 ms)
Within a menu, you can jump from one parameter to the next by pressing and releasing
the shift key. The sequence - which is fixed - is shown in the table below.
● Press and hold down the shift key (> 2.5 s)
Press and hold down the shift key to switch from the RUN menu to the SET menu and
vice versa.
– RUN → SET
– SET → RUN
