ξGeneral consideration must be given to the steering system and its geometry before starting the RRU installation. Many factors must be contemplated for a practical solution. The information given here is for guidance only, although where a maximum or a minimum value is given these must be adhered to.
ξMount the rru on a flat surface next to the tiller arm or steering quadrant; construct a small platform if necessary.
