Installation
Fitting the lens Fig. E
1 Remove the lens mount cap.
2 Screw in the lens (not supplied), and turn it until it is secured.
Note
Clean the optical filter with a commercially available blower brush to remove
dust.
Using a tripod Fig. F
To use the tripod, install the tripod adaptor VCT-ST70I (not supplied) on the
camera module.
Use a tripod screw with a protrusion (4) extending
from the installation surface, as follows:
ISO standard: Length 4.5 mm ±0.2 mm
ASA standard: Length 0.197 inches
Note
If you install a tripod adapter (not supplied), use the screws provided.
Connecting the camera cable Fig. G
Connect the IEEE1394 camera cable to the camera connector and the 1394
interface connector of your computer. When you connect the cable, press
the push button on the connector and insert the connector until it snaps into
place.

Phenomena specific to CCD image sensors
The following phenomena that may appear in images are specific to CCD
(Charge Coupled Device) image sensors. They do not indicate
malfunctions.
White flecks
Although the CCD image sensors are produced with high-precision
technologies, fine white flecks may be generated on the screen in rare
cases, caused by cosmic rays, etc.
This is related to the principle of CCD image sensors and is not a
malfunction.
The white flecks especially tend to be seen in the following cases:
•when operating at a high environmental temperature
• when you have raised the gain (sensitivity)
Vertical smear
When an extremely bright object, such as a strong spotlight or flashlight, is
being shot, vertical tails may be produced on the screen, or the image may
be distorted.
Aliasing
When fine patterns, stripes, or lines are shot, they may appear jagged or
flicker.
Vertical lines
When you shoot a dark object at a high temperature, vertical lines may
appear all over the image.
This phenomenon is characteristic of a camera with ultraviolet-range
sensitivity.
