INSTALLATION AND SERVICE GUIDE
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
"Detailed Troubleshooting," next.
