second with Code 3 or 4 the Logical Combination Rule will appear as follows.

define up to 10 different code types;
•

types.
The maximum number of groups to be defined for each rule string is 15.

Read Messages parameter group is displayed requiring the definition of a Local No Read String
for each group.
