Neewer F100 7 Inch Camera Field Monitor HD Video Assist Slim IPS 1280x800 4K HDMI Input 1080p with Sunshade and Mini Ball Head for DSLR Cameras Note: NP-F battery and 12V adapter NOT included. Troubleshooting 1. Cannot turn on the monitor Be sure you are powering the monitor with a 12V AC adapter. Or with an NP-F battery, check if it is fully charged and correctly installed. When power is on, the LED indicator will turn red. Wait for 6s and press the power button, the LED indicator will turn blue. 2. There is noise in my recorded videos Press and hold the “<” button to decrease the volume close to zero. Doing so can eliminate noise in your videos. 3. The monitor displays “No Signal” or the signal connection is unstable Try another HDMI cable. Connect the monitor to your PC via the HDMI cable and see if your monitor has a signal. Change the signal output of your camera. Make sure the signal is in HDMI mode, and the monitor’s input signal supports your camera’s output signal. The monitor will lose its signal when the camera is off. Please make your camera’s display stay on longer (disable auto-off if possible) or turn on the camera’s live view function. Find [HDMI] > [Output resolution] in the camera settings and set it to AUTO.
