Orient so that the best reception is obtained.

*If you connect an outdoor FM antenna to this unit, do not connect the indoor FM antenna to this unit.

*The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall.

*The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit.

mOptional outdoor FM antenna

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.

*Use a 75-ohm/300-ohm antenna adapter (not included) or a 75-ohm antenna adapter (not included) for connections.

Notes for FM antenna installation

●To minimize automobile ignition noise, 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 at least two meters (6.6 feet) from reinforced concrete walls or metal structures.

mOptional outdoor AM antenna

In steel buildings or at a great distance from the transmitter, it may be necessary to install an outside long wire antenna.

GND terminal

For maximum safety and minimum interference, connect the GND terminal to a good earth ground. A good earth ground is a metal stake driven into moist earth.
