NOTE: Under most conditions, no setting of switches will be required. Please read the details of each switch before making any adjustments.

1BLC - Back Light Compensation

OFF (Default setting) - Disables the BLC mode.

BLC - Enables the BLC mode. If a bright backlight is present, the objects in the picture may appear dark or as a silhouette. BLC enhances objects in the center of the picture, and can be used to improve picture quality; in a fixed scene.

2AGC - Automatic Gain Control OFF - Disables the AGC mode.

AGC (Default setting) - Enables the AGC mode. Automatically adjusts the image to compensate for changes in light levels. Most scenes benefit from AGC operation.

3OPT - Optima

OFF (Default setting)

OPT - Boosts the video by 3 dB. Only use if your video signal appears weak on your monitor.

4ESC - Electronic Shutter Control OFF - Disables the ESC mode.

ESC (Default setting) - Enables the ESC mode. The ESC function automatically changes the sensi- tivity of the camera by varying the electronic shutter speed according to the amount of incident light. Electronic shutter speed range is 1/60 to 1/100,000. Should only be used with an AID or manual iris lenses. Do not use with an AIV type lens.

5AIV/AID - Auto Iris Lens Mode Selector

The switch setting is determined by the type of lens used:

AIV - Video controlled Auto Iris lens. Disable the ESC mode when using an AIV type lens. AID (Default setting) - DC controlled Auto Iris lens.

6INT/LL - Internal/Line Lock

Line Lock (LL) (Default setting) - Locks the vertical frame to the power supply frequency. Eliminates vertical roll caused by multiple cameras connected to the same switching device. Internal - Locks the vertical frame to the internal oscillator. Use with DC or unstable AC.

NOTE: If DC power is applied when the INT/LL switch is in the LL position, the camera will not function. Switch the mode to INT.
