How to Reset to Factory Settings
Screen brightness information
Press and hold the 'DAB/FM' & 'Preset 1' buttons for more than 2 seconds. The Horizon 2 is now reset to the default factory settings.
If the screen appears dark, try repositioning the Horizon 2 for the light sensor to work to the fullest. In some positions, the Horizon 2 cannot effectively detect the ambient light level in the room.
