# Parameters
|
||
|
|
|
||
|
|
The _Parameters_ screen allows you to find and modify any of the parameters associated with the vehicle.

## Finding a Parameter
|
||
|
|
|
||
|
|
The parameters are organized in groups. Select a group of parameters to view by clicking on the buttons to the left (in the image above the _Battery Calibration_ group is selected).
|
||
|
|
|
||
|
|
You can also _search_ for a parameter by entering a term in the _Search_ field. This will show you a list of all parameter names and descriptions that contain the entered substring (press **Clear** to reset the search).
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## Changing a Parameter
|
||
|
|
|
||
|
|
To change the value of a parameter click on the parameter row in a group or search list. This will open a side dialog in which you can update the value (this dialog also provides additional detailed information about the parameter - including whether a reboot is required for the change to take effect).
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
::: info
|
||
|
|
When you click **Save** the parameter is automatically and silently uploaded to the connected vehicle. Depending on the parameter, you may then need to reboot the flight controller for the change to take effect.
