Preparing Your Receiver

Connecting the Antennas

In many areas, the supplied indoor AM loop and FM antennas provide satisfac- tory reception.

AM Antennas

Assemble the supplied AM antenna’s base by swinging the base in the direction of the arrow and inserting the antenna’s bottom tabs into the base’s slot. If the receiver is in a rack or on a shelf and there is no room for the AM loop antenna, use two screws (not supplied) to mount the base on the wall or another location as shown.

Attach the antenna wires to the AM LOOP ANTENNA and (ground) terminals (upper two terminals).

Place the antenna on a flat surface and rotate it for the best AM reception.

Notes:

• Keep the AM loop antenna connected even when you use another indoor antenna or an outdoor AM antenna.

Ensure that the antenna does not touch the receiver or any other metal object.

Do not place the antenna near a CD player, a personal computer, or a TV set.

If the wire between your AM loop antenna and receiver is too short, you can add extra wire, available at your local RadioShack store.

You can also use a RadioShack shortwave antenna kit (Cat. No. 278-758), which makes an excellent outdoor AM antenna. Connect the outdoor AM antenna wire to the receiver’s AM terminal, as shown.

FM Antennas

Note: For the best results, use 75-ohm coaxial cable to connect an outdoor an- tenna to the receiver.

Connect the supplied FM antenna to the FM UNBAL 75Ω terminal as shown, then extend it.

For better FM reception, you can also use a rabbit-ear TV antenna (for indoor use only). To connect the TV antenna to the receiver, you need a VHF/UHF/FM splitter (not included). RadioShack stores carry a full line of quality antennas and antenna connection accessories.
