If these errors occur, the object dictionary will be reset to its default
values.
 After the object dictionary has been changed and object dictionary
contents are then changed, execute a Store Parameter command (Index
= 1010 (Hex)).
 If the object dictionary has not been changed, execute a Restore
Parameter command (Index = 1011 (Hex)).
