halogen lamps, and that AGC on the menu is set to

image may be displayed out of focus and
mode switching may not perform automatical-
ly.

Default: 30 seconds
The camera determines whether to switch the
mode when the time set for holding a picture
motionless on the screen has elapsed.

Note: A pan/tilt, zoom or focus operation will
