(The WDR feature will function in normal light intensities.) � The right edge of the screen may temporarily jiggle. � For temperatures higher than the recommended temperature, the slow shutter may not work correctly.

WHITE BALANCE

Default setting: ATW

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. MANUAL.. : Use this setting when manually adjusting the white balance for the current lighting (color temperature). 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. Use this setting when using the white balance that has been adjusted manually.

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.
