4. To adjust the unit for plumb, place the bubble-level tool on a flat surface of the collector
and, with one hand, tilt the unit until the bubble in the leveling tool is away from the wall.
It is not necessary to center the bubble in the circle.
Note If you do not have a bubble-level, adjust the unit so that the bottom is parallel with
the ground. This ensures the antenna is plumb (perpendicular to the ground, pointing
down) when you attach it in the next procedure.
5. With the other hand, move in a cross (X) pattern and torque all four bolts to between 50-
and 60-inch pounds.
Caution To achieve the clamping force needed to withstand 100 MPH winds, torque the
four hex-head bolts to the specification listed. If the bolts are under-torqued, the necessary
clamping force may not be achieved, and if they are over torqued, the brackets can become
over-stressed, which could also reduce clamping force.
Attaching the RF Antenna to the New Collector
Both the POTS version and the CDPD version of the collector have an RF antenna that attaches
to the collector bottom. The CDPD version has a second antenna that attaches to the collector top.
You will install the CDPD antenna in the next procedure if you are installing that version of the
collector.
Caution The two antennas differ in appearance and function. You can distinguish the
CDPD antenna from the RF antenna by the two additional knobs on the base of the CDPD
antenna. Installing an antenna in the wrong place may damage the collector and will cause
it to fail to work as intended.
To Attach the RF Antenna to the New Collector
1. Align the RF antenna with the N-connector on the bottom of the unit.
2. Press the antenna onto the connector and turn the antenna clockwise until it no longer turns
andisfirmlyinplace.
