Operating Precautions (continued)

●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 phenomenon normal to a solid-state image pickup device (CCD) and is not a malfunction.

●The electronic shutter speed of the camera has been set to 1/50 *(1/60) 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 *(50 Hz), change the shutter speed to 1/ 120 *(1/100) second using the remote control unit. (Note that the sensitivity will deteriorate slightly.) *( ) : TK-C625U

●When the camera is used to monitor the same position over many hours (e.g. continuously for 24 hours a day) the contact resistance of the panning mechanism may increase. This may cause the picture to be affected by noise interference or the remote control operation becoming unstable. To prevent this from happening, once a week, turn the system off and on to initialize the camera and clean the contacts.

●Do not touch the lens on the dome cover directly by hand. Contamination of the cover will lead to deterioration of the picture quality.

●Since the dome cover is of a hemispherical shape, the picture tends to become distorted at the edges of the hemisphere. The edges of the hemisphere is masked for this camera. When the camera is tilted and pointed in the horizontal direction, therefore, edges of the hemisphere may enter the angle of view, hence causing the upper end of the screen to appear dark and the image to go out of focus. In this case, use the TILT LIMIT settings (Page 25) to prevent capturing the above areas.

●When an object is located near a light source or contains a large difference in brightness, a ghost may interfere with the picture. This phenomenon is due to the characteristics of the dome cover and the built-in lens and is not a malfunction.

●In particular, manual or auto pan operations near the TELE end may cause the screen to appear shaky (rotation is not smooth). This phenomenon is due to the characteristics of the motor and is not a malfunction.

●Observe the following points when carrying out maintenance of the camera.

•Turn the system off before proceeding.

•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 becomes excessively contaminated, clean it with a lens cleaning cloth (or tissue) moistened with a solution of neutral detergent in water.

●If this camera is stored in an environment with low temperature with its power turned off, a message indicating "PLEASE WAIT. NOW WARMING-UP." will appear blinking on the monitor when the power is turned on, and it will start to warm up. Warming up is complete after the internal parts of the camera reaches an appropriate temperature, after which normal operation of the camera is possible. Please wait for a while until the warming up message disappears.

8Zooming operation

The following phenomena are due to the characteristics of the built-in lens and are not malfunctions.

●Focus may deviate slightly upon stopping a zoom operation near the Tele end manually or using a preset selection.

●Manual zooming operation may not always be smooth.

●When a preset selection is made, the image may go out of focus for a second during the zoom operation.

8Preset positions

●The zooming position of the camera can be set to a total of 100 preset positions, including the home position.

8Note 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 chargeable even when they are replaced before the termination of the warranty period.

●Zoom lens assembly

●Zooming operation : 2 million times

●Focusing operation : 4 million times

●Slip rings : 5 million operations

●Cooling fan : Approx. 50,000 hours

8Note on auto focusing

Although this unit incorporates a one-push auto-focusing system and EASY AF functions, auto-focusing may sometimes be impossible depending on the object and camera setup. In this case, adjust the focusing manually.

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 example 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.
