1. Determine if the camera dome is receiving
power. Look for evidence such as a picture on
the video monitor or dome movement.
2. Detach the dome to access the environmental
PC board.
Note: Power to fans comes from the dome.
Fans will not function with the dome removed.
CAUTION: Touch the metal housing before
handling the environmental PC board.
3. Verify power is reaching the housing. Press
and hold switch SW2 and observe the green
(ac power) LED; it should glow steadily. If not,
check power at the J-box and check that the ac
cable is plugged into connector P7 on the top
side of the environmental PC board.

screwdriver. Using a blade too wide can
damage connectors.
