This article describes how to use the Graphical User Interface (GUI) on the ENA amplifier.<br>
The user’s means of interaction with the amplifier is through the '''Menu Selection Knob'''.<br> 
The knob is located next to the display and can be turned clockwise and counter clockwise, as well as being pressed.

== Basic Navigation ==
Items in the menu system are selected by turning the '''Menu Selection Knob''':
* Clockwise rotation will move the “selector” to the right or down
* Counter-clockwise rotation will move the “selector” to the left or up <br>

Whether the selector is moved up/down or left/right depends on the current menu displayed.
* Press the menu selection knob to activate the selected menu item
* Press and hold the knob to return to the previous view <br>

To change or input the parameter values in the selected menu item:<br>
1. Turn the knob to move between the parameter fields <br>
2. Press the knob to select the parameter field <br>
* The field turns green to indicate that it is selected and ready for input value
3. Turn the knob to change the parameter value <br>
4. Press the knob to select the parameter value

'''Load Factory Default values''': To load default configuration and reset to DHCP, press and hold the menu selection knob for 20 seconds while booting up the Amplifier.

== Access Control ==
By default the display menu of the amplifier can be accessed without any pin code. However, it is possible to enable pin code access. Two levels can be defined, Read or Full Access.

For how to set a PIN code, see [[Password (ENA Amplifiers)]].
