D Image Sensor Cleaning Using camera controls during startup interrupts image sensor cleaning. Cleaning is performed by vibrating the low-pass filter. If dust can not be fully removed using the options in the Clean image sensor menu, clean the image sensor manually or consult a Nikon-authorized service representative. If image sensor cleaning is performed several times in succession, image sensor cleaning may be temporarily disabled to protect the camera's internal circuitry. Cleaning can be performed again after a short wait. ❚❚ ManualCleaning If foreign matter can not be removed from the low-pass filter using the Clean image sensor option in the setup menu (0 329), the filter can be cleaned manually as described below. Note, however, that the filter is extremely delicate and easily damaged. Nikon recommends that the filter be cleaned only by Nikon-authorized service personnel. 1 Charge the battery or connect an AC adapter. A reliable power source is required when inspecting or cleaning the low-pass filter. Turn the camera off and insert a fully-charged battery or connect an optional AC adapter and power connector. The Lock mirror up for cleaning option is only available in the setup menu at battery levels over H. 2 Remove the lens. Turn the camera off and remove the lens. n 331
