For best reception the transmitter and receiver must be aligned with the
flat-pitted faces back to back. The antenna in the receiver should face the
rear of the vehicle and the antenna in the transmitter should face the front
of the vehicle. RF signal can be picked up between the receiver and the
transmitter best by using this method.
