• To password protect operations, the lowest level security group out of the security groups enabled with a
password must be assigned to a user account.
The security levels, from highest to lowest, are Administrator > Operator > Reader.
Example: To password protect the operation to display Device Monitor, assign the Operator security
group to a user account. If a user account assigned to the Operator security group does not
exist, the operation is not password protected.
