An indicator (20) includes an indicator infrared transceiver (60b), direction signs, and directional information corresponding to the relative direction in a path from the indicator to each of the locations. The portable device (30) directly communicates the information corresponding to the selected location via the device infrared transceiver to the indicator infrared transceiver of the indicator to cause the indicator (20) to access the directional information and activate the appropriate direction sign to guide the user toward the selected location.
