The grey box is a immediate results transmitter which reads the data about punches directly from the punch device and send them to the finish where can be used by reporter to anounce preliminary results. The control transmitter (transmitting MOI --/---/..) and its antenna is located in an adjacent tree, about two meters above ground. The athletes find the control using their receiver (in fact the signals leads them to the antenn of control transmitter), they find the control (the color of control flag is orange/white because this combination is not present in the forrest), punch the card and the result trasmitter sends information about the presence of athlete to the finish.
