To add a new User-Defined set, select the General tab of the Program Options window and select New in the User-defined keys section
This will display an input window:
Enter a name for the name for the new User-Defined set e.g. “Adults” and select OK.
NOTE: This name is used as a file name so must not include any dots, hyphens or other characters that have special meaning.
An empty User-Defined set of this name will be added and will appear in the pull down list on the User defined keys section.
User-defined screens may now be added to this set.
