The keys have multiple assignments. Function assignments and key labeling change according to
the context of operator input. The designation of the current key function can be seen above the
key number in the footer area of the display. A short press on the key triggers the function once.

ond. The function of the key is triggered repeatedly while the key is held down. Autorepeat is
useful, for example, for fast incrementing of values when parameterizing the device.
