•Choose the user name you wish to change from the User drop-down list.

•You may not change a user name for an existing account. Instead, delete the existing account, as described in 5.6.5 - Delete a User Account (Administrators Only), and then add a user with the new name (see 5.6.2 - Create a New User Account (Administrators Only)).

•Enter a password for this user in the Password box. The password is case-sensitive and must be alphanumeric (spaces are allowed). Verify the password by entering it again in the Confirm Pass- word box.

•Specify the type of access privileges for this user by placing a check mark in the appropriate Access box:

•Read permits viewing only; users cannot make any changes, except to their own passwords.

•Write (includes Read access) allows access to all functions except other users’ accounts; users can view data, change configuration settings and change their own passwords.

•Administration (includes Read & Write access) provides full access to all functions, includ- ing creating and modifying other user accounts.

•Specify whether the Web interface will log off automatically after the computer is idle for a speci- fied time in the Inactivity Timeout drop-down list. The choices are Never or 1, 2, 5, 15 or 60 min- utes. This setting is applied to all users.

•Click Apply to make these changes effective. (To cancel the changes, click Reset.)
