p Protection
The protection feature lets you prevent changes to part programs, the
tool table and datum 0. See Fig. II.16.
Two soft keys are available ON and OFF. The default is OFF. To protect
a feature use the ON soft key.
When the program protection is set to ON, part programs cannot be
changed or saved.
Setting the tool table to ON prevents it from being changed.
Setting the datum 0 to ON prevents datum 0 from being changed.
The protection settings will be retained on a power cycle.

The COUNTER SETTINGS feature is the parameter where the
operator defines the user application for the readout. The choices are
for milling or turning applications. See Fig. II.17.
A FACTORY DEFAULT soft key appears in the COUNTER SETTINGS
choice of options. The operator will be prompted to press YES to set
parameters to factory default settings or NO to cancel and return to
previous menu screen.
