Observing the system documentation
Some operations with the project may require in-depth knowledge about the specific system
on the part of the operator. If you use jog mode, for example, proceed with care. Refer to
your system documentation to find any additional information on this topic.
Operation feedback from operating elements
The HMI device provides operation feedback as soon as it detects that an operating element
has been selected. This operation feedback is independent of any communication with the
controller. Therefore, this operation feedback does not indicate whether the relevant action is
actually executed or not.

CAUTION
Touch only one operating element on the screen at a time.
Do not press more than two function keys at the same time.
Exception: The keyboard shortcut <CTRL+ALT+DEL> can also be used with the system
keys. Note that the "Lock Task Switching" option can be activated in the project in the
Runtime settings of the HMI device.
