is not visible, set the lens for proper exposure by adjusting the ALC

can range between AVG (average) or PK (peak). A mid-range
setting is appropriate for most applications.
For ALC adjustments:
AVG
PK
For Level adjustments:
Adjust the Level control for the best picture during the day. A night
adjustment may not provide the proper setting for controlling the
light during the day.
F. Set the back focus of the camera before the final adjustment of the
video level.

a) If the lens oscillates between open and closed under bright
lights, slowly turn the gain adjustment counter clockwise until
the oscillating stops.
b) Increase the light getting to the camera by adjusting the level
control and re-adjusting the gain control as necessary.

To slow the reaction of the lens to changing light, set
the range to the AVG setting to average the video level
from the camera. Use when there are bright spots in the
picture such as lights or glare from the sun.
To increase the speed of the lens reaction to the
changing light, set the lens adjustment to PK so the
lens will adjust to the brightest or peak object in the
video. Use this setting if you want to see the brightest
object and not the background objects.
