The 'Lock' icon indicates your Display Group is in Protected Mode, which protects your displays or display groups from being controlled by others using the remote control or removable USB/SD cards to access the Display features or your campaigns.
To Activate Protected Mode
1. Protected Mode can be activated in the settings tab of your Display Group by going to the 'Display' tab, then selecting a Display Group, and going to the 'Settings' tab.
2. Turn on Protected Mode, create your 4-digit password, and then press 'Save Changes' to activate.
Note that by using this feature, you will prevent your Displays from any change made by other users. To unlock the Displays, the user will have to type your 4 Digit password to access the settings and use the remote control.
