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.
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.

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.
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.
