in a recess on the back of the camera (fig. 4-4).
You can change its setting by sliding it with the
help of a sharp pencil or toothpick.
The connection cable______________
The connection cable supplied with the camera
has a length of 10 metres (33 feet). If the
distance between camera and monitor happens
to be shorter or longer, you can easily make a
special cabrte, using a standard coaxial cable
(available at your dealer’s) and the extra coaxial
plugs supplied with your camera (fig. 7). You
can actually cover a distance of 100 metres (330
feet) or more, depending on the quality of the
cable you are using.
Changing the length of the cable
If the distance is shorter than 10 metres (33 feet)
and the extra length bothers you, you can
shorten the cable. Measure the required length,
starting from the cinch plug (fig. 6) to make sure
that the cinch plug is included with the shorter
cable you are making. Do not make the cable
too tight but allow a little leeway. Then mount
the male coaxial plug (fig. 7) at the other end.
If the distance between camera and monitor is
larger than the length of the connection cable,
you can make an extension cable, using both
separate plugs supplied with this set (fig. 7) and
the required length of a good quality coaxial
cable (75 Ohm), available at any TV store.
If you want to bridge a longer distance, you
should use a special cable extension set with RF
booster amplifier, which will allow a distance
from camera to monitor of up to 600 metres
(1800 feet).
The lens________________________
Your camera is equipped with a standard CS
lens mount and supplied complete with an 8
mm, F 1.3 lens with a viewing angle of 34°
horizontally and 26° vertically. The lens has a
C-mount thread and is fitted with a C/CS adapter
ring. It means that you can actually use anyone
of a wide range of both C-mount and CS-mount
lenses with either a fixed iris or manual iris.
When choosing a C-mount lens, you should use
the C/CS adapter ring. Automatic iris lenses
cannot be used.
When using a lens with manual iris adjustment,
you should, in principle, set it at its largest
aperture.
Using a different lens
The CCD sensor in the camera head is very
sensitive to dust, if you ever remove the lens
from the camera you should always point the
camera downward to minimize possible deposit
of dust. Never touch the sensor and/or use any
cleaning materials. Only use clean, dry air to
blow any particles from the surface of the
sensor. Special aerosol air-spray cans are
available at any good camera store.
