❚❚Manual Cleaning

If foreign matter can not be removed from the low-pass filter using the Clean image
sensor option in the setup menu (0301), 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.

filter.
Turn the camera off and insert a fully-charged EN-EL15 battery or connect
an optional EP-5B power connector and EH-5b AC adapter.
The Lock mirror up
for cleaning option is only available in the setup menu at battery levels over
