This camera comes with a built-in AGC circuit. The sensitivity increases automatically at a dark place and the screen may appear grainy. This is not a malfunction.

While the AGC is activated, if a transceiver which causes strong electromagnetic wave is used near the camera, the picture may suffer from beat.

Please use the camera more than five meters from such transceivers.

You may hear some noise during power on and when the screen is switched between the color and the black and white mode, because of the movement of the optical filter switching motor. Also, the image will be somewhat distorted.

The beat may sometimes appear on the screen if gain is raised when the line lock is in use, but the phenomenon takes place due to the fluctuation of power frequency and is not a malfunction.

When this camera is used in the White Balance ATW (automatic tracking) mode, the color tone may differ slightly from the actual color due to the principle of the automatic tracking white balance circuit. This is not a malfunction.

If a high brightness object (such as a lamp) is shot, the image on the screen may have white vertical tailings. This is a characteristic of the CCD known as the smear phenomenon and is not a malfunction.

When a high brightness object is shot, sometimes undulations can be observed on the vertical lines of the object. However, this phenomenon is peculiar to the camera and is not a malfunction.

Caution for operating the VIDEO IRIS lens

If the LEVEL dial of the VIDEO IRIS lens is set to a low level (L position), a malfunction - such as the hunting phenomenon where the iris opens and closes involuntarily - can occur. In such a case, first set the LEVEL dial on the lens to the H position, and then adjust it to an optimum level while checking the video signal.

The cable stopper on the terminal block can come off sometimes. Therefore, be sure to take enough time and fix the cable securely.

This camera achieves optical performance by using specified lens (1/3 inch size) conformed to CCD size. However, some general lens may not meet this specification (effective image circle is small or optic displacement is big). When such lens are used, negative effects such as shading may occur.
