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
coax-
ial cable.
Note: If your antenna has 300
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
terminal.
2. With a stripping tool, remove about 1
1
/
2
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 cen-
ter 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
FM UNBAL 75
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 ser-
vice 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.
