on the right. Strip one-quarter inch of insulation from the wire
prior to termination. To remove a wire, turn the above screw
counter-clockwise to loosen the connector's grip on the wire.
To insert a wire, push the bare wire into the connector and turn
the above screw clockwise to lock the wire into place.

5. Phone Jacks (RJ11 Connectors):
RJ connectors, as seen in
Figure 13
on the lower right, are
similar to the telephone connectors found in homes and are
used on the ends of flat RJ11 cable. In order to remove this
plug from the jack, depress the small clip on the underside of
the plug.
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.

6. Quick Connect Jack:
The display uses quick connect jacks for the connection of the
temperature sensor, the client radio, and connection of the
primary to the secondary or mirror display. The quick connect
jacks are located on the back of the display and when not used
the attached cover should be kept closed.
To attach the cable to a jack, make sure to line up the plug to
match the jack, push the plug in then turn the outer collar to
lock in place.

jack.
