If the Screen Saver is enabled on the camera, the camera's screen will turn off after 30 seconds of recording. The camera is still on and recording (indicated by the flashing red LED), it's just the screen that's been turned off (black). This is used by certain drivers to prevent distraction.  1) Turn the Dash Cam on 2) Stop it recording (by pressing the red circle) 3) Go into Settings (the button in the top left) 4) Go into Setup settings 5) Scroll across to ‘Screen Saver’ 6) Enable/ disable the Screen Saver here There's also a setting available called 'Speed Display'. This will allow the camera to act as above with Screen Saver, but instead of just a black screen, the vehicle's current speed will be displayed instead.  1) Turn the Dash Cam on 2) Stop it recording (by pressing the red circle) 3) Go into Settings (the button in the top left) 4) Go into Setup settings 5) Scroll across to ‘Screen Saver’ 6) Select the Speed Display setting. 6) Enable the Speed Display here.
