Cleaning the Filter
The low-pass filter is extremely delicate and easily damaged. It is recommended that
you have the filter cleaned by Nikon-authorized service personnel. Should you choose
to ignore this warning and clean the filter yourself, follow the steps below.
1
Raise the mirror as described in the first five steps of “Determining Whether the
Filter Requires Cleaning.” Note that an EH-4 AC adapter (sold separately) is
required for this operation; if no adapter is available, you will need to take the
camera to a Nikon-authorized service center for cleaning.
2
Remove dirt and dust from the filter with a blower.
Do not use a blower-brush, as the bristles could dam-
age the filter. If using an aerosol blower, hold the can
upright to prevent liquid from falling on the filter. Dirt
that can not be removed with a blower can only be
removed by Nikon-authorized personnel. Under no
circumstances should you touch or wipe the filter.
3
Display the Mirror Lock-up for CCD Cleaning sub-menu as described above
under steps 3 and 4 of “Determining Whether the Filter Requires Cleaning” and
select the OFF option. The mirror will return to the down position and the
shutter curtain will close.
4
Turn the camera off and replace the lens or body cover, then unplug the AC
adapter.
