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-authorized service representative once every one to two years,
and that it be serviced once every three to five years (note that fees
apply to these services). Frequent inspection and servicing are
particularly recommended if the camera is used professionally. Any
accessories regularly used with the camera, such as lenses or optional
flash units, should be included when the camera is inspected or
