Troubleshooting
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,
then turn the camera on again. In the event of continued malfunction, contact
your retailer or Nikon-authorized service representative. Note that disconnecting
the power source as described above may result in the loss of any data not
recorded to internal memory or the memory card at the time the problem
occurred. Data already recorded will not be affected.

Cause/Solution
• When camera is in playback mode, press the A
button.
• When menus are displayed, press the d button.
• Battery is exhausted.
• When flash lamp blinks red, flash is charging.
• The intended subject is one with which autofocus
does not perform well.
• Set AF assist in the setup menu to Auto.
• Turn camera off and then on again.
• Use flash.
• Use vibration reduction and motion detection.
• Use D (Best Shot Selector).
• Use a tripod to stabilize the camera (use with the self-
timer for best results).
Smear may occur when the lens is aimed at bright
subjects. When using the multi-shot 16 shooting and
movie modes, we recommend that you avoid shooting
when direct sunlight, reflected sunlight, or electric
lights are in the display.
Flash is reflecting off particles in air. Turn flash W (off).
• Flash is W (off).
• Some scene modes that cannot turn on flash are
selected.
• Smart portrait mode selected, with Blink proof set
to On.
• D mode is selected.
