1. Determine if housing and eyeball assembly
is receiving power.
Look for evidence such as a picture on the
video monitor or dome movement.
2. Remove housing and eyeball assembly to
access environmental PC board.
Note: Power to fans comes from housing and
eyeball assembly. Fans will not function with
this assembly removed.
CAUTION: Touch metal housing before
handling environmental board.
3. Verify power is reaching housing.
Press and hold switch SW2 and observe the
green (ac power) LED. Green LED should glow
steadily. If not, check power at J-box and ac
cable plugged into connector P7 on other side
of environmental PC board.
CAUTION: Connector screws on ac connector
are delicate. DO NOT over tighten them! Use a
2.5mm (0.1") slotted screwdriver. Wider blade
widths can damage connectors.
4. Check fan connector.
Is fan connector on other side of environmental
PC board plugged into connector P5?
YES: Replace fan/heater assembly 0400-
0935-01. Remove two screws to remove
assembly. Refer to items 20 and 21 in
Figure 18.

environmental board, and reconnect
housing and eyeball assembly. If the fans
still do not work, replace the fan/heater
assembly.
