The Manager control level is designed to be given to the top level user account, which has access to the Setup Wizard and Advanced pages of the Control Centre.
It also allows the user to modify all other user accounts. The Advanced control level does not give the user this ability.
You can use the help button on each page of the Control Centre to view articles in this help file if you get stuck. Of course, you can always check our online knowledgebase at kb.transactorsystems.com for further assistance. You can also get in contact with us from there.
