Important Safety Instructions

18.Use proper power sources – Plug the product into a proper power source, as described in the operating instructions or as marked on the product.

19.Avoid power lines – Use extreme care when installing an outside antenna system to keep from touching power lines or circuits, as contact with them may be fatal. Do not install external antennas near overhead power lines or other electric light or power circuits, nor where an antenna can fall into such circuits or power lines.

20.Ground all outdoor antennas – If an external antenna or cable system is connected to this product, be sure the antenna or cable system is grounded. This will provide some protection against voltage surges and built-up static charges.
