Connecting an Outdoor FM Antenna

If you cannot achieve good reception with the supplied indoor FM antenna, try a commercially available out- door FM antenna instead.

FM 75

Notes:

•Outdoor FM antennas work best outside, but usable results can sometimes be obtained when installed in an attic or loft.

•For best results, install the outdoor FM antenna well away for tall buildings, preferably with a clear line of sight to your local FM transmitter.

•Outdoor antenna should be located away from possi- ble noise sources, such as neon signs, busy roads, etc.

•For safety reasons, outdoor antenna should be situated well away from power lines and other high-voltage equipment.

•Outdoor antenna must be grounded in accordance with local regulations to prevent electrical shock haz- ards.

■Using the 75/300-ohm Antenna Adapter (Australian model only)

The 75/300-ohm antenna adapter can be used to connect an FM antenna using either 75-ohm coaxial cable or 300-ohm twin-core flat cable.

■Connecting 300-ohm Flat Cable

1	Using a screwdriver, loosen the
	two screws on the adapter, wrap
	the bare wires around the
	screws, and then retighten them,
	as shown.
2	Plug the adapter into the 75 Ω socket.

3	Move the small wire inside the adapter
	from position A to position B, as shown.

	Position B
4	Insert the central conductor (1), as
	shown, and use a small pair of pliers to

clamp the shielding and outer insulation sections of the cable (2), as shown.

Make sure the shielding is not touching the central conductor.

5 Refit the adapter’s cover, and then plug the adapter into the 75 Ω socket.

■Using a TV/FM Antenna Splitter

It’s best not to use the same antenna for both FM and TV reception, as this can cause interference problems. If cir- cumstances demand it, use a TV/FM antenna splitter, as shown.

Connecting an Outdoor AM Antenna

If good reception cannot be achieved using the supplied AM loop antenna, an outdoor AM antenna can be used in addition to the loop antenna, as shown.

■Connecting 75-ohm Coaxial Cable

2	Using your fingernails or a small screw-
	driver, lever the adapter’s tabs outward

and remove the cover, as shown.

Outdoor AM antennas work best when installed outside horizontally, but good results can sometimes be obtained indoors by mounting horizontally above a window. Note that the AM loop antenna should be left connected.

Outdoor antenna must be grounded in accordance with local regulations to prevent electrical shock hazards.
