9. Check spring finger connector on I/O board by
connecting housing and eyeball assembly to
original base to verify contact between spring
fingers and CPU board (under cap). Does
dome produce video and respond to
commands?
YES Spring fingers may not have seated
properly. Reconnect housing and eyeball
assembly.
NO Replace I/O board.
If routine troubleshooting did not solve the
problem, the manufacturer strongly recommends
you ship the entire dome (including base, if an I/O
board is used) to the National Service Center
(NSC) for service. See page 22 for phone
numbers.
If you must perform detailed troubleshooting, use
extreme care when disassembling parts! See
