gramming Console was connected. Ensure that the PC is in PROGRAM mode
before you enter the password. When the password is entered, the PC will
shift to the mode set on the mode switch, causing PC operation to begin if the
mode is set to RUN or MONITOR. The mode can be changed to RUN or MON-
ITOR with the mode switch after entering the password.
