Preparing Your Receiver
Connecting the Antennas
In many cities, the supplied indoor AM loop and FM antennas provide adequate
reception.
AM Antennas
Assemble the included 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. Then
attach the antenna wires to the
AM LOOP ANTENNA
and
GND
terminals.
Place the antenna on a flat surface and rotate it for the best AM reception.
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.
Notes:
• Keep the AM loop antenna connected even when you use another indoor
antenna or an outdoor AM antenna.
• Ensure the antenna does not touch the receiver or other metal objects.
• 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
Connect the supplied FM antenna to the
FM UNBAL 75
Ω
terminal and extend it
as shown.
For better FM reception, you can also use a rabbit-ear TV antenna (for indoor
use only) or an outdoor VHF TV antenna. 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 outdoor antennas and antenna connection accesso-
ries.
Warning: To prevent injury, read and fol-
low all cautions and warnings that
accompany the outdoor antenna.
Note: For the best results, use 75-ohm
coaxial cable to connect an outdoor
antenna to the receiver.
