Abstract
A method and apparatus for visually and audibly verifying Call signal generation in a vehicle detector. A generated Call signal drives a visible display, such as a discrete LED, an LED display composed of multiple discrete LEDs, or an LCD display. The same generated Call signal also controls the operation of an audible tone generator so that an audible tone is generated whenever the vehicle detector generates a Call signal. The audible tone generation permits a single technician in the field to check the vehicle detector for correct Call signal generation in response to vehicle movement in the vicinity of the associated detector loop
