Connecting Antenna —Continued
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 from tall buildings, preferably with a clear line
of sight to the 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
The 75/300-ohm Antenna Adapter is not supplied with
American and European models.
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.
Plug the adapter into the 75 Ω socket.

■ Connecting 75-ohm Coaxial Cable
1
Strip and prepare the
75 ohm coaxial cable,
as shown.
2
Using your fingernails or a small screw-
driver, lever the adapter's tabs outward
and remove the cover, as shown.
3 Move the small wire inside the adapter
from position A to position B, as shown.

4
Insert the central conductor (
shown, and use a small pair of pliers to
clamp the shielding and outer insulation
sections of the cable (
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.

Outdoor AM antennas work best when installed horizon-
tally outside, 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.
