This operation is used to restore the status of all bits which have been force
set or reset. It is possible in MONITOR or PROGRAM mode only.
RUN

Before changing the contents of I/O memory, be sure that the changes will not
cause equipment to operate unexpectedly or dangerously. In particular, take
care when changing the status of output bits. The PC continues to refresh I/O
bits even if the PC is in PROGRAM mode, so devices connected to output points
on the CPU Unit, Expansion Units, or Expansion I/O Units may operate unex-
pectedly.

2. Press the SET and then the RESET Key. A confirmation message will ap-

Note If you mistakenly press the wrong key, press CLR and start again
from the beginning.
3. Press the NOT Key to clear the force-set/reset status of bits in all data areas.
This operation is used to convert word data displays back and forth between
