Caution This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot
minimum clearance from the antenna while the system is operating. Wherever possible, shut
down the RAN before servicing the antenna.
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails
without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent
or curved to a radius of less than 2 inches (50 mm).
Caution: Exterior surface of the RAN may be hot. Use caution during servicing.
Caution: Hazardous voltages are present. The inverter located in the HUB FIR converts 12
VDC to 120 VAC. Use caution when servicing the equipment.
SAFE WORKING DISTANCES
The Digivance CXD antenna, which is mounted on top of a pole, radiates radio frequency
energy.
For the Occupational Worker, safe working distance from the antenna depends on the workers
location with respect to the antenna and the number of wireless service providers being
serviced by that antenna.
Emission limits are from OET Bulletin 65 Edition 97-01, Table 1 A.
RF fields are computed using equation 3 from the same document.
RF fields below antenna are computed using equation 10 with F=0.3.
Combining the PCS and cell bands was done in accordance with OET Bulletin 65, page 35
(last paragraph).
WORKER LOCATION BELOW ANTENNA * BESIDE ANTENNA
One Band 10.2” 32.3”
Two Bands 14.3” 45.3”
Three Bands
* “Below” is defined as a 100 degree cone, 50 degrees each side of the
utility pole, with the tip of the cone at the base of the antenna.
Should the criteria for safe working distance not be met, the power amplifiers must be turned
off at the site where work is to be performed prior to commencing work.
