The TNC is now ready for operation in the Manual Operation mode.
The reference points need only be crossed if the machine
axes are to be moved. If you intend only to write, 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 MARK soft key in the Manual
Operation mode.
