15. A method to verify the performance of a police band radar detector comprising the steps of:
-
a) transmitting, through an electromagnetic field transmitter apparatus, an electromagnetic signal of field strength no greater than 500 microvolts/meter at 3 meters from the transmitter apparatus to an adjacent radar detector device; b) positioning the transmitter apparatus at a distal location from the radar detector under test until loss of signal inactivates alert circuitry; c) utilizing the distal location as a distance standard for performance of the radar detector device.
