PREPARATION FOR WORKING WITH VIDEO CAMERA
Connecting to a video tape recorder

In order to record video and sound with a video tape recorder, it's necessary to
perform following operations (see fig.1 and 2):
a) prepare video tape recorder according to the operation manual (in 1-2 minutes
after turning video tape recorder power on, a luminescence should appear on a
viewfinder display 4 of the video camera);
b) remove the cover from the lens, direct the lens to the object and, watching
the picture in the viewfinder eyepiece 4, set a most clear and contrast picture,
the same time adjusting a lens diaphragm;
