126 Technical Notes / Caring for the Camera

Turn the camera off . The mirror will be lowered and the shutter curtain will close. Re-
place the lens or body cap.
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 AF-assist illuminator will
blink to warn that the shutter curtain will close and the mirror will be lowered after about two min-
utes. 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 D80, however, is designed to be used with inter-
changeable lenses, and foreign matter may enter the camera when lenses are removed 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 (available separately; 123) or the
clean image options available in some third-party imaging applications.
Servicing the Camera and Accessories
The D80 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 inspec-
tion and servicing are particularly recommended if the camera is used professionally. Any accessories
regularly used with the camera, such as lenses or optional Speedlights, should be included when the
camera is inspected or serviced.
