Preparing Your Receiver
For the best radio reception, use an outdoor antenna. Follow these steps to
connect an outdoor FM antenna to the receiver using 75 cable.
Note: If your antenna has 300 twin-lead cable, consult your local Radio Shack
store for the correct adapter.
1. Disconnect the supplied FM antenna from the receiver’s
FM UNBAL 75
terminal.
2. With a stripping tool, remove about 1
1
/
2
inches of the cable’s outer insula
-
tion to expose the cable’s shielding.
3. Fold back the insulation from the inner insulation.
4. Remove about 1 inch of the inner insulation from around the center wire.
5. Pull the shielding to one side. Connect the center wire to the receiver’s
FM
UNBAL 75
terminal. Twist the shielding to secure any loose wire strands,
and connect it to the
GND
terminal.
Note: Grounding is not necessary for reception, but we recommend it to avoid
damage from lightning when you use an outdoor FM antenna and for better FM
reception. Use a separate piece of thick polyvinyl insulated wire to connect the
GND
terminal to an earth ground such as a metal cold-water pipe.
Warning: Never connect a wire to a gas pipe for grounding since sparks might
ignite the gas.
Warning:
To prevent injury, read and fol-
low all cautions and warnings that
accompany the outdoor antenna.
Caution:
The cable’s shielding should
only touch the
GND
terminal.
