Preparing Your Receiver
Warning: To prevent injury, read and fol- low all cautions and warnings that accompany the outdoor antenna.
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
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 outdoor antenna ca- ble’s outer insulation to expose the cable’s shielding.
3.Fold back the outer insulation from the inner insulation.
4.Remove about 1 inch of the inner insulation from around the center wire.

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 
terminal to the building’s power grounding electrode system.
Warning: Never connect a wire to a gas pipe for grounding since sparks might ignite the gas.
