Preparing Your Receiver

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.

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.

1.Disconnect the supplied FM antenna from the receiver’s FM UNBAL 75Ω terminal.

2.With a stripping tool, remove about 11/2 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.

Ground

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.
