Operating Precautions
Storage and Location of Use
䢇 This camera has been designed for indoor use. When you use it outdoors, be sure to use a housing or the like.
䢇 Do not install or use the camera in the following places.
● In a place exposed to rain or moisture.
● In a place with vapor or oil, for example in a kitchen.
● When the ambient temperature rises above or falls below the acceptable range (from
-10 I to 50 I)
● In a place at which corrosive gases are emitted.
● Near a source of radiation, X-rays, strong radio waves or magnetism.
● In a place subject to vibration.
● In a place with excessive dirt.
䢇 Using this unit or cables connected to this unit at places at which strong radio waves and magnetism are emitted (e.g. near a radio, TV, transformer or motor) may give rise to noises in the image and changes in its color.
Maintenance
䢇 Turn off the power before performing maintenance.
䢇 Clean the camera with a soft cloth. Wiping it with thinner or benzene may melt the surface or cause it to fog. For tough stains, wipe using a cloth that is dipped into a neutral detergent diluted with water, followed by wiping with a dry cloth.
Energy Conservation
䢇 When the camera is not in use for a long time, turn off the power of the system for safety and energy conservation reasons.
10
TK-C925_EN.book Page 11 Thursday, November 23, 2006 4:33 PM
Others
䢇 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.
䢇 While the AGC is activated, if a transceiver which causes strong electromagnetic wave is used near the camera, the picture may suffer from beat.
䢇 Please use the camera more than five meters from such transceivers.
䢇 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.
䢇 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.
䢇 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.
䢇 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.
䢇 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.
䢇 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.
䢇 The cable stopper on the terminal block can come off sometimes.
Therefore, be sure to take enough time and fix the cable securely.
䢇 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.

Precautions regarding fall prevention
● Special attention is required when installing the camera to the wall or ceiling. You should not engage in the installation work yourself. Ask a professional to do the job, since the fall of the camera can result in injuries and accidents.
● When installing the camera on a fixer, pan/tilt unit and the like, make sure to install it firmly using a rotation-preventive hole to prevent fall.
● To prevent fall, connect the camera to a section with sufficient strength
(ceiling slab or channel) using a fall prevention wire.
● Pay attention to the length, strength, routing and material (insulation properties) of the fall prevention wire used.
● Use the black screw (M3 x 6 mm) on the back of the camera for the installation of the fall prevention wire. Using other screws of different sizes may damage the inside.

Memo:
● When near-infrared illumination is used, a B&W screen may switch to a color screen if the object reflects light excessively. To perform switching with higher accuracy, we recommend that you use the settings mentioned in
AControl by B&W/Color switching signal from externalB (A Pg. 54).
● In the case of B&W/Color mode, the lens performance may cause the image to be out of focus when the illumination of the object is near-infrared light. In this case, use a lens that is compatible with near-infrared light.
