CONNECTIONS
■ Connecting a coaxial cable to the
75-ohm/300-ohm antenna adapter
(included for U.K. model only)
1 Open the cover of the
included 75-ohm/300-ohm
antenna adapter.
2 Cut the external sleeve
of the 75-ohm coaxial
cable and prepare it for
connection.
3 Cut the lead wire and
remove it.
4 Insert the cable
wire into the slot,
and clamp it with
pliers.
5 Snap the cover into place.
■ Notes on the 75-ohm coaxial and
the 300-ohm feeder cables
Consult with your dealer or authorized service center
about the best method of selecting and erecting an outdoor
FM antenna. The choice of the feeder cable is also
important. Flat ribbon-shaped twin-lead cable performs
well electrically, and is cheaper and somewhat easier to
handle when routing it through windows and around
rooms. Coaxial cable is more expensive, does a much
better job of minimizing interference, is less prone to the
effects of weather and close-by metal objects, and is
nearly as good a signal conductor as feeder cable,
particularly for foam-type coaxial cables. Coaxial cable is
somewhat more difficult to install at the point where the
cable enters the building. If coaxial cable is selected, make
sure the antenna is designed to be used with that type of
cable.
• To minimize interference from automobile ignition, locate the
antenna as far from heavy traffic as possible.
• Keep the feeder cable or coaxial cable as short as possible. Do
not bundle or roll up excess cable.
• The antenna should be placed at least 2 meters (6.6 ft) from
reinforced concrete walls or metal structures.
■ FREQUENCY STEP switch
(Asia and General models only)
Because the interstation frequency
spacing differs in different areas, set
the FREQUENCY STEP switch on
the rear panel of this unit according to
the frequency spacing in your area.
• North, Central and South America:
100 kHz/10 kHz
• Other areas: 50 kHz/9 kHz
Before setting this switch, disconnect this unit’s AC power
plug from the AC wall outlet.
