APPENDIX
SAFETY INFORMATION
CAUTION
MAINTAIN PRESCRIBED SAFE DISTANCE WHEN STANDING IN FRONT OF A RADIATING ANTENNA.*
*Reference FAA Advisory Circular #20-68B
MAXIMUM PERMISSIBLE EXPOSURE LEVEL (MPEL)
FAA advisory circular AC 20-68B defines the method for determining the MPEL boundary. All personnel should remain beyond the distance indicated in the illustration below. Manufacturers are required to calculate two distances; the MPEL boundary is determined by the greater of these two distances. The first distance is the near field/far field boundary which is the distance from the antenna that it takes for the beam to form. For the RDR-4000 this distance is 14 feet (4.27 meters). The second is the distance where the radiation level exceeds the U.S. Government standard of 10 milliwatts per square centimeter. For the RDR-4000 this distance is 11.8 feet (3.58 meters) from the antenna. In TEST mode the system transmits two 550 microsecond pulses at the beginning of the test sequence and the safe distance is 0.8 inches (2.1 centimeters) from the antenna during this period. The safe fuel distance is 3.5 feet (1.07 meters) from the antenna.
