LOCKING
2 99 Locking of the conguration
0: Conguration unlocked
(The unit cannot be started up; the unit type
parameters may be changed).
1: Conguration locked
(The unit can be started up by pressing the
"On/O󰀨" push button on the console. The
unit type parameters may no longer be
modified. The number of times the
conguration is unlocked is counted.)
