A Note on Electronically-Controlled Cameras
In extremely rare instances, unusual characters may appear in the monitor 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, taking care to avoid burns, 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. If the problem persists after
removing the battery from the camera, contact your retailer or Nikon-authorized service
representative.
