TRVR has two different user levels - 'Administrator' and 'User'. An 'administrator' has access to unit configuration menus and additional system privileges, while 'users' can only search, monitor and archive calls.
If you can only access the search and monitoring menus, and NOT the settings menu (at the TRVR unit) or configuration tab (in TRVR Remote Manager), it means you are logging in with a 'user' password.
If you require access to the system configuration, you will need to contact the company or person who set up your TRVR, and ask them to provide you with the 'administrator' password.
