The TNC is now ready for operation in the Manual Operation mode.
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 pop-up window, you may cut
off the power supply to the TNC
The reference points need only be crossed if the machine
axes are to be moved. If you intend only to edit or test
programs, you can select the Programming and Editing or
Test Run modes of operation immediately after switching
on the control voltage.
You can cross the reference points later by pressing the
PASS OVER REFERENCE soft key in the Manual
Operation mode.
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!
