■Condition Summary

This screen shows the filter conditions that have been created so far. It allows you to select any undefined condition to add, or to select any defined condition to delete (You can not modify a condition - you must delete the condition then add a new one to make changes). You do not have to add filters in consecutive order (that is, you can skip condition numbers.) And you can delete conditions from the middle. The conditions are used in the filter in order of smallest condition number to greatest condition number and unused condition numbers are simply ignored.

■The Add button returns you to the appropriate filter condition screen so you can define the next condition.

■The Delete button returns you to this screen unless you have just deleted the last condition, in which case you go to the

Delete Filter/Add Condition screen.

■When you are finished defining conditions, press the Save Filter button. This completes the filter and takes you to the Filter Summary screen.
