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 75Ω coaxial cable.
Note: If your antenna has 300Ω twin-lead cable, consult your local RadioShack
store for the correct adapter.
1. Disconnect the supplied FM antenna from the receiver’s
FM UNBAL 75
Ω
terminal.
2. With a stripping tool, remove about 1

inches of the outdoor antenna
cable’s outer insulation to expose the cable’s shielding.
3. Fold back the shielding 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

Ω
terminal. Twist the shielding to secure any loose wire strands,
and connect it to the
FM UNBAL 75
Ω
terminal.
Note: Grounding is not necessary for reception, but we recommend it for better
FM reception and to avoid damage from lightning when you use an outdoor FM
antenna. Use a separate piece of thick polyvinyl insulated wire to connect the
terminal to the building’s power service grounding electrode system.
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 ac-
company the outdoor antenna.
Caution:
The cable’s shielding should
only touch the terminal.
