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 phenom-
enon is caused by a strong external static charge. Turn the camera off , re-
move and replace the battery (note that the battery may be hot) or discon-
nect and reconnect the AC adapter, and turn the camera on again. If the
problem persists, turn the camera off and press the reset switch (see right;
note that this resets the clock). In the event of continued malfunction, con-
tact your retailer or a Nikon-authorized service representative.
