Password protection
Elements of password protection
Password protection consists of three elements
• Password level,
• User group,
• Password.
Password level
Each menu item is assigned a password level. Password levels are numbered
with 0, 1, 2 and 3.
Menu items are assigned to different password levels in order to assure that
specific menu items can only be changed by authorized users.
User group
The definition of a user group is that every user that belongs to it has access
entitlement at certain password levels, i.e. can make changes to the menu
items at these levels.
Some user groups are set-up at the factory.
A user group can be made up of one or more users.
Password
Every user group set-up in the system has a password.
The password consists of six digits which can be entered via the numeric
keypad.
Passwords are pre-assigned for the factory-set user groups.
