NOTE: Any excess antenna cable should be located outside of Rough-in.

In most locations the antenna supplied with the rough-in frame provides adequate AM reception; however, in rural or weak signal areas, a separate AM antenna may be required. Refer to the following instruction when selecting and connecting an AM antenna.

1.Refer to Figure 19. Move the auxiliary antenna selector switch to the AM position.

2.Connect 50 feet of 22 ga. insulated wire to the screw terminal marked AM ANTENNA.

3.Run the wire from the master station location to the attic. Fasten the insulated wire at one end of the attic; stretch the wire to its full length and fasten at the opposite end.

Fasten the insulated wire at several locations between ends to prevent sagging.
