GPS and GSM signals penetrate glass, plastics and other non-conductive materials. The GPS antenna must not be
covered with conductive material in the direction of reception of the signal.
Warning: Some vehicles have metal-plated windscreen. These glasses do not allow electromagnetic wave
propagation. In these cases, use a roof antenna or consult the location of the antenna with the manufacturer. There
are areas without the metallization in some metalized windscreens which can be used for antennas.

Dallas chip reader is used to identify the driver in the vehicle. When the unit is activated the LED in the center of
the sensor is permanently lit. The driver is identified by attaching the Dallas chip to the reader. The unit records the
chip code and the sensor light goes out. Logging out can be done by reattaching the same chip or turning off the
ignition. The sensor has five wires but only four are used. Usually, select the red light and therefore connect the
brown sensor wire. For green light connect the green wire. Some sensors from other manufacturers may have
different color marking on the wires
