Switch-off
To prevent data from being lost at switch-off, you need to shut down
the operating system of the TNC as follows:
 Select the Manual Operation mode.
 Select the function for shutting down, confirm again
with the YES soft key.
 When the TNC displays the message NOW IT IS SAFE
TO TURN POWER OFF in a superimposed window, you
may cut off the power supply to the TNC.
Inappropriate switch-off of the TNC can lead to data loss.
Remember that pressing the END key after the control
has been shut down restarts the control. Switch-off
during a restart can also result in data loss!
