JVC C205U Instruction Manual - Page 4

Features Ⅲ The camera uses a high-resolution 380,000 pixel (U type) / 440,000 pixel (E type), high-sensitivity CCD to realize high picture quality with horizontal resolution of 535 TV lines and S/N50dB. Ⅲ Dome-type design allows application in various locations. Ⅲ Built-in backlight compensation feature to improve the quality of video taken under backlight conditions. Ⅲ A 4inch square electrical box compatible Ⅲ Built-in white-spot correction feature Ⅲ Before starting an important recording, be sure to perform a test recording in order to confirm that a normal recording is possible. Ⅲ We do not accept liability for the loss of a recording in the case of it becoming impossible to record due to a problem in the video camera, VCR or video tape. Ⅲ We do not accept liability for any damage to the camera in cases when it is dropped because of incomplete installation due to not observing the installation instructions correctly. Please be careful when installing the camera. Operating Precautions ● To save energy, when it is not being used turn the system's power off. ● This camera has been designed for indoor use. It cannot be used outdoors. ● This camera has been designed exclusively to be hung from the ceiling. It may malfunction if it is placed on a surface or if it is tilted. ● 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 soot, for example in a kitchen. • In a temperature outside the operating temperature range (-10°C to 50°C). • Near a source of radiation, X-rays, strong radio waves or magnetism. • In a place where corrosive gasses are generated. • In a place subject to vibration. • In a place with excessive dirt. ● If this camera and the cables connected to this camera are used where there are strong electromagnetic waves or where there is magnetism present, for example near a radio or TV transmitter, power transformer or an electric motor, the picture may produce noise and the colors may be affected. ● This camera incorporates an AGC circuit. As a result, when it is used under low light conditions, the camera sensitivity is automatically boosted and the picture may look uneven. This is not a malfunction however. ● The white balance setting when used under a fluorescent lamp should be ATW (Auto White). ● When this camera is used in the ATW mode, the recorded colors may be slightly different from the actual colors due to the operational principles of the auto-tracking white balance circuit. This is however not a malfunction. E-4 ● If a high-intensity object (such as a lamp) is shot, the image on the screen may have vertical lines (smear) or blur (blooming) at its periphery. This is a characteristic of the CCD, and is not a defect. ● Do not touch the dome cover of the lens directly with your hand, contamination of this cover will lead to a deterioration of the picture quality. ● Observe the following when carrying out camera maintenance. • Turn the power OFF before proceeding to carry out maintenance. • Clean the dome cover lens using a lens wiper cloth (or a tissue). If it is contaminated seriously, clean the contaminated part with a cloth (or a tissue) which has been soaked in a solution of water and a neutral detergent. Safety Precautions • Installation of this unit requires expertise. Please contact your dealer for details. • The ceiling to mount the TK-C205 has to be strong enough to support ten times the weight of this product. If the ceiling is not strong enough, make sure to apply reinforcement to the ceiling before installation. • Be sure to tighten the screws and nuts securely, Insufficient tightening may cause the unit to fall from its mount. • The unit is to be powered by a DC 12 V or an AC 24 V power supply. The AC 24 V power supply should conform to the following: Class 2 only (U type) Isolated power supply only (E type) E-5 English
