since both zones are the same. A dome operator can see where the backlight compensation zone will average in the field-of-view.

Electronic Shutter (AUX 22, 23)

The camera's electronic shutter covers a range of 1/60 second (1/50 second for PAL units) to 1/10,000 second in 261 steps (311 steps for PAL units). As the electronic shutter speed increases, the time allowed during each video field for light to collect on the CCD decreases, resulting in a loss of sensitivity. However, higher shutter speeds tend to produce a "stop action" effect on moving images, greatly increasing the camera's dynamic resolution.

Increase Electronic Shutter Speed: Issuing this command will turn on the electronic shutter, and increase the shutter speed by one step. (AUX 22 - On.)

Decrease Electronic Shutter Speed: Issuing this command will turn on the electronic shutter, and decrease the shutter speed by one step. (AUX 22 - Off.)

Electronic Shutter Off: Issuing this command will disable the camera's electronic shutter. (AUX 23 - Off.)

Electronic Shutter On: Issuing this command will turn on the camera's electronic shutter. The shutter speed will be at the last set position. (AUX 23 - On.)

White Balance (AUX 30, 31, 32, 35)

Auto White Balance On: Issuing this command turns on the automatic white balance. The white balance setting adjusts continuously as the color temperature of the scene changes. This mode is recommended for situations where the color temperature of the scene varies during shooting. Continuous white balancing may not produce optimum color rendition when little or no white is present in the scene. (AUX 30 - On.)

Perform "Push Button" White Balance: Take the following steps to perform a "push button" white balance:

1.Aim the camera at a white object, such as a white wall or a piece of paper. The white object should fill the entire field of view of the camera.

2.Issue the command (AUX 30 - Off.). The picture should turn white within a few seconds. Continuous automatic white balancing is now disabled.

Turning on the manual white balance disables the automatic white balance. There are 107 steps of adjustment for changing either the red or blue content of the picture.

Manual White Balance - Increase Red: Issuing this command increases the red content of the picture by one step. (AUX 31 - On.)

Manual White Balance - Decrease Red: Issuing this command decreases the red content of the picture by one step. (AUX 31 - Off.)

Manual White Balance - Increase Blue: Issuing this command increases the blue content of the picture by one step. (AUX 32 - On.)

Manual White Balance - Decrease Blue: Issuing this command decreases the blue content of the picture by one step. (AUX 32 - Off.)

Fixed 3200 K White Balance On: Issuing this command turns off the automatic mode, and sets the white balance to approximately 3200 K. (AUX 35 - On.)

Fixed 5500 K White Balance On: Issuing this command turns off the automatic mode, and sets the white balance to approximately 5500 K. (AUX 35 - Off.)

Hue Adjustment (AUX 33, 34)

For most applications it is not necessary to make any hue adjustments to the camera. If you do need to make hue adjustments, be aware that by improving the color rendition of one hue, you are probably degrading the color rendition of some other hue. Depending on the trade-offs required by each application, this may or may not be acceptable.

R-Y Hue Increase: Issuing this command will shift red hues toward magenta by one step. (AUX 33 - On.)

R-Y Hue Decrease: Issuing this command will shift red hues toward yellow by one step. (AUX 33 - Off.)

B-Y Hue Increase: Issuing this command will shift blue hues toward cyan by one step. (AUX 34 - On.)

B-Y Hue Decrease: Issuing this command will shift blue hues toward magenta by one step. (AUX 34 - Off.)

Factory Default (AUX 40)

The camera can always be returned to its original state, as shipped from the factory. (AUX 40 - On.)

Factory Defaults: Issuing this command will reset the camera hues to their factory adjusted values, turn on the AGC and the auto white balance, turn off the electronic shutter and the backlight compensation, and put the camera in line-lock mode with a phase delay of zero degrees.
