Precautions for Correct Operation
Note on consumable parts
The following parts are consumable and should be replaced after a certain number of hours or a count of operations. The service lives given below are only typical values. They may vary depending on the operating environment and conditions.
Note that the replacement of consumable parts is charge- able even when they are replaced before the termination of the warranty period.

Note on auto focusing
Although this unit incorporates a
Objects and images with which auto focusing may be difficult:
•When the image brightness is extremely high.
•When the image brightness is extremely low.
•When the image brightness varies continuously (for ex- ample when the object is a flashing light).
•When the image contrast (difference between bright and dark) is very poor.
•When the image does not contain a vertical contour component.
•When vertical stripe patterns recur on the screen.
Camera setups with which auto focusing may be difficult:
•When the AGC is activated and the image is coarse.
•When SENSE UP is activated and the image contains only little motion.
●To save energy, turn the system power off whenever it is not in use.
●This camera has been designed for indoor use.It cannot be used outdoors.
●This camera has been designed to be hung from a ceiling with its base uppermost. Do not install it in an upside down position on a surface or at an angle, as this may cause a malfunction or a no- ticeable shortening of its service life.
●Do not install or use the camera in the following locations.
•In a place exposed to rain or water.
•In a place containing vapor or oil soot, for example in a kitchen.
•In a place outside the operating temperature range
•Near a source of strong radio waves or magnetism, radiation or
•In a place where corrosive gasses are generated.
•In a place subject to vibrations.
•In a place with excessive dust.
●Insufficient ventilation of the camera may cause a malfunction. Be careful not to block ventilation to the camera.
This unit radiates heat from the panel surfaces (top panel and side panels). Do not install it in a place where a heat pool may form, such as near a wall.
●Do not install the camera in a place exposed to cold air, for exam- ple near to the air outlet of an air conditioner. Otherwise, moisture may become condensed inside the dome cover.
●Do not point the lens at a strong light source, for example the sun, doing so may cause the camera to malfunction.
●The camera incorporates an AGC circuit. As a result, when it is used under low light conditions, the camera gain may increase automatically. This makes the picture appear uneven , however this is not a malfunction
●When equipment that generates strong magnetism such as a trans- ceiver is used near to the unit while the AGC circuit is ON, beat noise, etc may interfere with the picture. If a transceiver or similar equipment is used, keep it at a distance of at least 3 metres away.
●In auto iris mode, when the AGC circuit is ON, varying the iris with the iris control button may not change the picture brightness. This is due to the automatic gain boost by the AGC circuit. In this case, set AGC to OFF or use the manual iris mode.
●In auto iris mode, the iris control button may not function under certain brightness conditions (i.e.when a sufficient amount of light cannot be obtained). In this case, set the iris mode to manual.
●When the camera is used in ATW (Auto White balance) mode, the colours captured by the camera may differ from the actual colours being shot due to the mechanics of the
●If a very bright object (such as a lamp) is being monitored, the picture may contain vertical lines (smear) above and below the bright object in the picture.This is a normal phenomenon for solid- state image pickup devices (CCD) and is not a malfunction.
●The electronic shutter speed of the camera has been set to 1/50 second at the factory. If the camera is used under a fluorescent light source in an area with a local power frequency of 60 Hz, change the shutter speed to 1/120 second using the remote con- trol unit. (Note that the sensitivity will deteriorate slightly.)
However, if the ExDR function is ON, the flicker may not disap- pear.
●When the camera is used to monitor the same position over many hours ( e.g. continuously for 24 hours a day) the contact resist- ance of the panning mechanism may increase. This may cause the picture to be affected by noise interference or the remote con- trol operation becoming unstable.To prevent this happening, once a week, turn the system off and on in order to initialize the camera and to clean the contacts.
●Do not touch the lens on the dome cover directly by hand. Con- tamination of the cover will lead to deterioration of the picture quality.
●Since the dome cover is of a semispherical shape,the picture is distorted at the edges of the semisphere.When the camera is pointed for
●When an object is located near a light source or contains a large difference in brightness, ghosting may occur. This phenomenon is due to the characteristics of the dome cover and the
●Observe the following points when carrying out maintenance of the camera.
•Turn off the power to all equipment to be used before proceed- ing.
•Clean the dome cover using a lens cleaning cloth (or tissue). The dome cover may become stained in a very short period in certain operating environments. If the dome cover lens be- comes excessively contaminated, clean it with a lens cleaning cloth (or tissue) moistened with a solution of neutral detergent in water.
Zooming
When zooming is stopped near theTELE end during manual operation or by selecting a preset position, focusing may de- viate slightly. In addition, the manual zooming operation may not always be smooth.
These phenomena are due to the characteristics of the built- in lens and are not malfunctions.
Preset positions
•The zooming position of the camera can be set to a total of 100 preset positions, including the home position.
•The TILT position can be set and operated only between 0° to 90° even when the item “FLIP” is set to DIGITAL. (A TILT position between 91° and 180° cannot be set or operated. The message "INVALID POSITION (TILT) will appear on the screen if a larger TILT position than 90° is set. )
