Appendix
If problems occur
If a problem occurs that causes interference or difficulty within the telephone
network, disconnect the Freedom System (FP-200 autopatch unit) from the tele-
phone network by removing the modular plug from the telephone jack (Phone
Line Input) on the Freedom System base unit.
Neither you nor your distributor should attempt to repair the Freedom System base
unit, the FP-200 autopatch PC board, or the RR-454 PC board. Any unauthorized
repair may seriously affect the compliance with the rules under which the unit is
registered. Remove the unit from service and contact Rain Bird through your Rain
Bird Distributor.
FCC radio regulations
Assignment and use of 25 KHz frequency offsets
A. Frequencies separated by 25 KHz (wideband) from regularly assignable
frequencies in the 450-470 MHz band may be assigned in the land mobile
services in accordance with the following conditions:
1. All stations will be licensed as mobiles, but they may serve the functions of
base, fixed, or mobile relay stations. Such stations are limited to two watts
output power.
2. All operations should be on a secondary, non-interference basis to the
primary operations. They are not entitled to protection from such stations.
3. Where the primary channel availability is indicated in more than one service,
the frequency coordination requirements in section 90.175 apply in all
services. (See section 90.555 [a] for identification of service abbreviations.)
4. Wide area operations will not be authorized. The area of normal day-to-
day operations is described in the application. It states the maximum
distance from a geographical center (latitude and longitude).
5. Applications for stations under this part must provide a statement of
proposed use, but are otherwise exempt from any limitation on the
number of frequencies assignable contained elsewhere in Part 90.
6. Antennas of mobile stations used as fixed stations communicating with one
or more associated stations located within 45 degrees of azimuth shall be
directional and have a front to back ratio of at least 15 dB. Except as
provided below, the height of the antenna used at any mobile station
serving as a base, fixed or mobile relay station may not exceed seven meters
(20 feet) above the ground.
•
There is no limit on the length or height above ground of any
commercially manufactured radiating transmission line when the trans-
mission line is terminated in a non-radiating load and routed at least
seven meters (20 feet) interior to the edge of any structure or is routed
below ground level.
•
Only sea-based stations and central alarm stations operating on
frequencies allocated for central station protection operations may use
antennas mounted not more than seven meters (20 feet) above the
man-made structure, including antenna structures.
B. You can coordinate other special frequencies with Rain Bird and Cara
Enterprises (801) 278-9728.
