Safety Instructions - Installation
To prevent rainwater from running along the outdoor antenna cable and
entering the house, be sure the outdoor portion of the cable hangs down
below the point of entry.
If rainwater enters the product, it may cause an electric shock or fire.
If you are using an outdoor antenna, be sure to put sufficient distance
between your antenna and the electrical wires nearby so that they would
not come in contact with each other in case the antenna is knocked over
by strong wind.
A knocked-over antenna may cause injury or an electric shock.
