6.7.2 Changing Locked Configuration Parameters

The parameters preceded by a right angle bracket (>) are vital parameters, those parameters
that are used to calculate the UCN.. The current values for these parameters are displayed in
gray text. These parameters may be reset in the field using the DT utility after unlocking the
configuration parameters. When vital parameters are changed, a new UCN must be calculated
by office personnel and transmitted to the field personnel.
To unlock the configuration parameters, click the Edit button
at the top of the screen (Figure 6-17). A prompt is displayed
indicating that unlocking the parameters will place the
system in a restrictive state and that a new UCN is required
to make the system operational. Click the Yes button to
unlock the parameters. When unlocked, the parameters
displayed in gray text change to green.
