Fiber Optic Connectors:

end. To remove the fiber plug, push it toward the
board and twist it counter-clockwise until you can pull
the plug from the jack.

6. RJ11/RJ45 Connectors:
RJ connectors, as seen in
Figure 13
, are similar to the
telephone and LAN connectors found in homes and
businesses. In order to remove this plug from the jack,
depress the small clip on the underside of the plug.

Connector
Before replacing an RJ connector, spray it with
DeoxIT
™
contact cleaner to remove any foreign matter
that may cause signal problems. In addition, apply a
generous amount of CaiLube
™
protector paste to the
plug before inserting it into the jack. This paste will
protect both the plug and the jack from corrosion.
7. Quick Connect Jack:
The display uses quick connect jacks for the
connection of the signal termination enclosure, and the
temperature sensor. There are three input and one
output quick connect jacks located on the back of
the primary display, and when not used the attached
dust cover should be kept closed.
