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 cable.

Note: If your antenna has 300Ω twin-lead cable, consult your local RadioShack store for the correct adapter.

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.
