Configuration Menus Configuration Menus are used for changing the settings on the controller/sensor.  Depending on the Preferences, either all points on the selected group e.g "Display Settings" are shown, or "Display Settings" shows sub-menus, and by selecting the sub-menu, the settings from the sub-menu are displayed. These screens have three buttons on the top of the screen:- "Reset Device"; soft starts the device (the setting changes are not stored) "Apply Changes"; stores the settings in the non-volatile memory of the device and resets the device. Note: this may disconnect bluetooth, if this happens press "Connect" to re-connect to the device "Refresh Data"; the submenus load automatically the latest values from the device (once). By pressing "refresh data" the values are refreshed from the device.  To back-up the device data to the phone/tablet, return to the Main Menu level and select Backup/Restore from the Top Right menu.
