lighting an object is changed, the white balance should be adjusted again by pressing the
AWC button.

lighting condition as the object to be shot
and zoom in to fill the screen with white.

When the AWC button is pressed for
approx. one sec., the white balance is
adjusted for the object being recorded.

During the time when the Auto White
function is operated, “AWC OPERA-
TION” is displayed (for approx. 0.5 sec.).
When the appropriate white balance is
acquired, “AWC OK” is displayed.
