Access Levels
The use of three access levels ensures that only authorized personnel can
read/edit sensitive system data. In order to enter access level 1, no password is
necessary, and only those screens accessible at that level will be displayed (see
also Table 2). In order to enter access levels 2 and 3, a corresponding password
must be entered.
