Troubleshooting If the camera fails to function as expected, check the list of common problems below before consulting your retailer or Nikon representative. ❚❚ Display Viewfinder is out of focus: Adjust viewfinder focus or use optional diopter adjustment lenses (0 36, 353). Viewfinder is dark: Insert a fully-charged battery (0 22, 37). Displays turn off without warning: Choose longer delays for Custom Setting c2 (Auto meter-off delay) or c4 (Monitor off delay) (0 273, 274). Unusual characters displayed in control panel: See "A Note on ElectronicallyControlled Cameras," below. Displays in control panel or viewfinder are unresponsive and dim: The response times and brightness of these displays varies with temperature. Fine lines are visible around active focus point or display turns red when focus point is highlighted: These phenomena are normal for this type of viewfinder and do not indicate a malfunction. A A Note on Electronically-Controlled Cameras In extremely rare instances, unusual characters may appear in the control panel and the camera may stop functioning. In most cases, this phenomenon is caused by a strong external static charge. Turn the camera off, remove and replace the battery, and turn the camera on again, or, if you are using an AC adapter (available separately), disconnect and reconnect the adapter and turn the camera on again. In the event of continued malfunction, contact your retailer or Nikon- authorized service representative. Note that disconnecting the power source as described above may result in loss of any data not recorded to the memory card at the time the problem occurred. Data already recorded to the card will not be affected. n 373
