Go to Administration > System Management > System Settings. If this is your first time viewing them, filter by number order by clicking on Setting ID twice. This will order the first setting, # -1, at the top of the column.
Begin reviewing them, reading the descriptions in order to decide if there are changes needed for your PIMSY system.
If you aren't sure about any of them, write the number down and during your next scheduled meeting the support team will go over them with you. You can also email support or call us about the settings in question.
