Memo
� When raising the gain, noise will appear in the screen for dark areas. � When in a dark area and setting AGC MODE to SUPER (�2) and up: � Video may temporarily lock or noise may be noticeable. � The entire screen may temporarily change from a dark to a bright state. � When especially dark, depending on light intensity, the Wide Dynamic Range (WDR) feature will not function. (The WDR feature will function in normal light intensities.) � The right edge of the screen may temporarily jiggle. � If the EASY D/N mode is turned on, the mode changes automatically to black and white in dark places. As the sensitivity increases, the image may look grainy and white spots may appear. When changing modes, bright portions of image may be emphasized but this is not a failure of the camera.

The white balance adjustment mode is selected. White balance can be adjusted for lighting with color temperature in the range between 2,500K and 10,000K. ATW : The unit will be in the Auto Tracking White Balance mode. The white balance will be adjusted automatically according to the color temperature of the lighting. AWB (SET) : When pressing the SET button (under 1 second), the white balance will be adjusted automatically for the current lighting (color temperature). The result of the white balance automatically adjusted will be stored in the unit memory. Use this setting when using the white balance that has been adjusted automatically.

When pressing the SET button, the screen for manually adjusting the white balance appears. ( Page 34) The result of the white balance manually adjusted will be stored in the unit memory.

Memo
� When adjusting the white balance for AWB (SET) or MANUAL, fill the entire screen with a white subject (such as paper, cloth, etc.). � If proper colors cannot be achieved in the ATW mode, use the AWB (SET) or MANUAL mode. � In some cases, proper white balance may not be achieved even in the MANUAL mode for artificial lightning such as fluorescent lighting, etc.
