[] 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, 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, contact your retailer or Nikon-authorized service representative.
