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. When you use it outdoor, be sure to use a housing and the like. ● 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. • When the ambient temperature rises above or falls below the acceptable range (from -10°C to 50°C). • Near a source of radiation, X-rays, strong radio waves or magnetism. • 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 colours 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. However, this is not a malfunction. ● While AGC activated, if use kind of transceiver which cause strong electromagnetic wave at close distance, picture might have influence for beat and etc. So please kindly use camera more than three meters apart from such transceivers. ● When this camera is used in the ATW mode, the recorded colours may be slightly different from the actual colours due to the operational principles of the auto-tracking white balance circuit. However, this is not a malfunction. ● 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. ● Observe the following when carrying out camera maintenance. • Turn the power OFF before proceeding to carry out maintenance. 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. ● TK-C1460U and TK-C1460E 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: TK-C1460U Class 2 only TK-C1460E Isolated power supply only ● Caution for operating the video iris lens In case the video iris lens is set to an extremely low level, malfunction - such as the hunting phenomenon in which the iris opens or closes unintentionally - can occur. In such a case, first set the "LEVEL" potentiometer on the lens to the H position (iris open), and then adjust it to an optimum level. (੬ Page 20) ● The cable stopper on the terminal block can come off sometimes. Therefore, be sure to take enough time and fix the cable securely. ● When a highly bright subject is shot, sometimes undulations can be observed on the vertical lines of the subject. However, this phenomenon is peculiar to the unit and is not a sign of malfunction. ● 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. ● You may hear some noise when the screen is switched between the color and the black and white, because the optical filter moves. Also, black vertical bands will appear on the screen. E-7
