Use a Reliable Power Source
The shutter curtain is delicate and easily damaged. If the camera powers off while the mirror is raised,
the curtain will close automatically. To prevent damage to the curtain, observe the following precau-
tions:
• Do not turn the camera off or remove or disconnect the power source while the mirror is raised.
• If the battery runs low while the mirror is raised, a beep will sound and the self-timer lamp will fl ash
to warn that the shutter curtain will close and the mirror will be lowered after about two minutes.
End cleaning or inspection immediately.
Foreign Matter on the Low-Pass Filter
Nikon takes every possible precaution to prevent foreign matter from coming into contact with the
low-pass fi lter during production and shipping. The D800/D800E and D4, however, are designed to
be used with interchangeable lenses, and foreign matter may enter the camera when lenses are re-
moved or exchanged. Once inside the camera, this foreign matter may adhere to the low-pass fi lter,
where it may appear in photographs taken under certain conditions. To protect the camera when
no lens is in place, be sure to replace the body cap provided with the camera, being careful to fi rst
remove all dust and other foreign matter that may be adhering to the body cap.
Should foreign matter fi nd its way onto the low-pass fi lter, clean the fi lter as described above, or have
the fi lter cleaned by authorized Nikon service personnel. Photographs aff ected by the presence of
foreign matter on the fi lter can be retouched using Capture NX 2 (available separately; to download a
free 60-day trial, visit the Nikon support website for your region) or the clean image options available
in some third-party imaging applications.
Servicing the Camera and Accessories
The camera is a precision device and requires regular servicing. Nikon recommends that the camera
be inspected by the original retailer or Nikon service representative once every one to two years, and
that it be serviced once every three to fi ve years (note that fees apply to these services). Frequent
inspection and servicing are particularly recommended if the camera is used professionally. Any ac-
cessories regularly used with the camera, such as lenses or optional fl ash units, should be included
when the camera is inspected or serviced.
