temperatures lower than minus 20 and higher than 50 C.
During storage, transportation and function don't direct video camera lens vertically down.
Don't arrange too long, more than 1 hour, sessions of steady objects, because the moving tube has
a picture "memory" effect.
Store the video camera with the lens cover closed.
Certain video camera shipments may contain schematic and constructive changes, which don't degrade
their parameters.

BRIEF DESCRIPTION
Video camera is intended for amateur video recording together with a following consumer video tape
recorders:
- "Elektronika-501-video"
- "Elektronika-502-video"
- "Elektronika-505-video"
- "Elektronika-508-video"
 

- "Elektronika-509-video" and others, that provide video camera with synchronization.

Video camera is forming a simplified television signal of black and white picture, synchronized to a video tape recorder, and a soundtrack signal for recording on a video tape recorder magnetic tape.
For recording a soundtrack there is a microphone 3 in a video camera case (fig. 1 and 2), directed to the scene being shot.
Video camera has a viewfinder 4, intended for the control of a quality of recorded scenes, and for the playback from the video tape recorders "Elektronika-501-video", "Elektronika-505-video",
"Elektronika-509-video" of a recordings made recently.
Inside the video camera handle there is a switch 7, intended for remote switching the tape drive mechanisms of a video tape recorders "Elektronika-501-video", "Elektronika-505-video" and "Elektronika-509-video".
Video camera is connected to a video tape recorder with a cable 4 (fig. 3), which is ended with connector 5.
Video cameras are shipped with a lenses, having constant focus distance - "Industar 50-2" or lenses with variable focus distances - "Meteor -5-1" and their modifications.
For the usage convenience, video camera has a belt.
Shooting with the video camera may be held both from "the hand", either from the unified tripod, therefore, there is a pit 6 for a tripo in the video camera handle (see fig. 1 and 2).

PREPARATION FOR WORKING WITH VIDEO CAMERA

Connecting to a video tape recorder

Before working with video camera plug a connector 5 (see. fig. 3) of a video tape recorder cable into a "CAMERA" jack 3, located on a panel of video tape recorder. When plugging in, orient the connector by the jack with direction key [strip?], and after connecotr with a slight push will enter the jack, then turning a cover ring clock-wise (2-3 turns), fix the connector in video tape recorder jack.

RECORDING

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;

R e m a r k s:
1. If the video camera is supplied with a lens of type "Industar 50-2", then do the diaphragm adjustments turning the ring 1 (see fig. 1), and the focus adjustments turning the ring 2. Set a desirable scale with lever 8.
2. If the video camera is supplied with a lens of type "Meteor 5-1", then do the diaphragm adjustments turning the ring 2 (see fig. 2), and focus adjustments turning the ring 1. Set a desirable scale with lever 8.
c) controlling the video tape recorder, that has a tape drive mechanism remote control, is performed pressing the switch 7 on the video camera handle, thereafter the tape drive mechanism is turned on, and, simultaneously, the indicator led behind the viewfinder eyepiece 4, which signal the recording mode, become lit. Recording termination is performed pressing the switch 7 second time, thereafter the led gets dark.
d) controlling the video tape recorder, that hasn't a tape drive mechanism remote control, is performed by operation controls, located at the video tape recorder panel.
During the next session, the video camera should be turned smoothly in order to be able to review on the viewfinder display the scene being recorded.
It's suggested not to be affected by capturing steady scenes, because in a difference of photography, the video recording gives an opportunity to show an action in it's dynamic. [Somehow non-technical language.]
 

In order to get quality soundtrack recording, provide a neccessary level of the sound recording, adjusting the distance between a sound source and the video camera microphone, doing in certain cases probe recordings.
For the quality sound recording during the session of type "interview", it's suggested to use external microphone, connecting it directly to the video tape recorder.

PLAYBACK
In order to play recording back, perform a tape rewind and set a video camera in convenient state
to watch the viewfinder screen, put the tape recorder into "playback" mode.

VIDEO CAMERA SERVICE

drives, generators, transformators and so on), in a conditions of too low or too hight
temperature, high humidity or extensive dust. To keep normal video camera function during a long breaks in
usage, store it in a standart package in a dry place with the temperature of 25 +/-15 C.
