• When using an RG-59U (3C-2V) cable, do not use it
on piping or air wiring.
• If you use a cable other than the type above, the
image or sync signal will be attenuated and will not be
transmitted correctly.

b Camera attachment
When attaching the camera, make sure to verify that the attachment surface will allow full
tightening of the screws. Plaster board, etc., may not give a strong enough attachment, and
it is recommended to use a reinforcement, or other method so that the screws are anchored
securely.

This normally does not need adjustment. If the picture is out of focus at the telephoto position,
adjust the flange-back position as described below.
adjust the flange-back position as described below.
When monitoring lighting or other extremely bright objects (which
exceed the maximum required illumination), smearing may occur in
the vertical or horizontal direction (either above and below the
high-brightness object or as a perpendicular band). In such a case,
adjust the angle of illumination and other factors while observing
the monitor.

b When a hunting reaction occurs
Under near infrared lighting or other similar conditions, hunting reaction may occur because the
Day/Night function is not carried out normally. In such case, refer to the following diagram for cable
connection to fix the image either to color or black-and-white by using an external switch, etc.
