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 sepa- rately), disconnect and reconnect the adapter and turn the camera on again. If the problem persists, press the reset switch (see right) and then reset the camera clock to the correct date and time (68). In the event of

continued malfunction, contact your retailer or Nikon 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.
