Nikon Camera F3AF - Manual (Page 85)

Caution:
1) When handling the F3AF with the DX-1 removed, be careful not to soil
or damage the electrical contacts at the bottom of the finder or the
matching ones inside the camera body at the top of the mirror box.
Aiso do not short-circuit them.
2) Do not pick up the camera by the finder only. The force may cause
damage to the camera.
3) To prevent dirt from getting inside the finder, always keep the eyepiece
glass attached.
4) When storing the DX-1 separately from the camera body, attach the
protective cover (supplied with the camera) to prevent the built-in finder
screen from becoming scratched.
