before consulting your retailer or Nikon representative.

(0 22, 176).

Information display does not appear in monitor: Shutter-release button is pressed halfway. If
information display does not appear when you remove your finger from shutter-release
button, confirm that On is selected for Auto info display (0 139) and that battery is charged.
Camera does not respond to controls: See “A Note on Electronically-Controlled Cameras,” below.
Viewfinder display is unresponsive and dim: The response times and brightness of this display vary
with temperature.
A 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.
