The connector is polarized and can only be inserted into the jack one
way.

. The EI switch should be in the OFF position.
E
. The A/I switch should be in the VIDEO position.
F
. Apply power to the camera.
G
. Adjust the focus ring on the lens for an optimum picture. If a picture is not
visible, set the lens for proper exposure by adjusting the ALC (automatic
level control) and level on the lens. The ALC setting can range between
Average (average) or PK (peak).
A midrange setting is appropriate for most applications.
For ALC adjustments:
AVG
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.
PK
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.
