The system controls access to the programmable options according to the programming password the
administrator enters. There are three password levels:
When programming passwords, the system will enforce the higher level password if
there are duplicate entries. For example, if you inadvertently set the level 3 (Installer)
password the same as either level 1 (System Administrator 1) or level 2 (System
Administrator 2), the system will enforce the level 3 password.
