A U bolt is included with each Alert. Using the U bolt , attach it to the
handle of the case. The case can then be attached to a pole.
In frost alert mode (Item #3450), the Cellular Alert should be installed
in the area that is most likely to have the first frost. The temperature
sensor should be at least three inches from the ground for an accurate
temperature.
In humidity mode (Item #3450H), the sensor
should be placed in an area that gives a rep-
resentative reading. The sensor and radiation
shield should also be attached to the pole us-
ing the bracket supplied.
In water mode (Item #3420W), the sensor
should be placed in a furrow. Take care that
the sensor grid is not touching the soil. Con-
tact with damp soil could trigger the alert con-
dition.
There is an LED light that shows through the outside of the case. The
light indicates what mode the cellular alert is in. The following chart
shows the patterns:
