tion (factory setting) is used under varying lighting conditions (such as outdoors) or fixed lighting

compensation is used in fixed lighting conditions to optimize the picture detail when there are
bright spots.

for AGC, switch 4 for electronic shutter control,
switch 5 for backlight compensation, and switch
