•Alarm output 1 relay : 200,000 times of operation

Note on auto focusing

Although this unit incorporates a one-push auto-focusing system and EASY AF functions, auto-focusing may some- times 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 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 com- ponent.

•When vertical stripe patterns recur on the screen.

Camera setups with which auto focusing may be diffi- cult:

•When the AGC is activated and the image is coarse.

•When SENSE UP is activated and the image contains only little motion.

•When electronic zooming is activated and the image does not contain a large enough contour component. (In the case of TK-C676 only)

Zooming

When zooming is stopped near the TELE end during manual operation or by selecting a preset position, focusing may deviate 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 electronic zoom can be preset up to x2.

However, if the electronic zoom menu on the screen is set to OFF even presetting the electronic zooming to x2 , the camera itself moves to the preset position without the electronic zooming being activated. (TK-C676 only)

•It is not permitted to preset the electronic zoom to a larger ratio than x2. The message "INVALID POSITION (D.ZOOM)" will appear on the screen if a larger ratio than x2 is set. (TK-C676 only)

•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. )
