Troubleshooting If the camera fails to function as expected, check the list of common problems below before consulting your retailer or Nikon-authorized service representative. Battery/Display The camera is on but does not respond: Wait for recording to end. If the problem persists, turn the camera off. If the camera does not turn off, remove and reinsert the battery or, if you are using an AC adapter, disconnect and reconnect the AC adapter. Note that although any data currently being recorded will be lost, data that have already been recorded will not be affected by removing or disconnecting the power source. Viewfinder is out of focus: Adjust viewfinder focus (0 11). If this does not correct the problem, select single-servo autofocus (AF-S; 0 100), singlepoint AF (0 103), and the center focus point (0 110), and then frame a high-contrast subject in the center focus point and press the shutterrelease button halfway to focus the camera. With the camera in focus, use the diopter adjustment control to bring the subject into clear focus in the viewfinder. If necessary, viewfinder focus can be further adjusted using optional corrective lenses (0 287). Viewfinder is dark: Insert a fully-charged battery (0 19, 46). Displays turn off without warning: Choose longer delays for Custom Setting c2 (Standby timer) or c4 (Monitor off delay; 0 263). Displays in control panel or viewfinder are unresponsive and dim: The response times and brightness of these displays vary with temperature. The viewfinder display turns red when a focus point is highlighted: This is normal for this type of viewfinder and does not indicate a malfunction. 301
