Setting up the AM Antenna
• Insert the claw on the bottom of the antenna into the hole in
the leg.
• Place the antenna on a level surface and rotate it to locate the
orientation that yields the best reception.
• Use th_ attachment hole in the leg to screw to wall or other lo-
cation, then insert the claw on the bottom of the antenna into
the hole in the leg (fixing the antenna in the direction that
gives the best reception).

NOTE FOR FM ANTENNA:
Stretch the antenna out to its full length, and affix it to a wall, etc.
NOTE FOR AM LOOP ANTENNA:
The antenna should be placed at a distance from the receiver, and
should not be allowed to touch metallic objects.
A void placing it near CD players, personal computers, television
sets, and other devices generating radio frequencies.
EXTERNAL FM ANTENNA
The main advantage of FM over AM is the quality of the broad-
cast signal. In order to benefit fully from the high signal quality of
FM broadcasts, it is recommended that a special-purpose FM an-
tenna be installed. In weak signal areas, a multi-element (3 ele-
ment, 5 element, 7 element, etc.) antenna should be used.
FM OUTDOOR ANTENNA CONNECTIONS
There are two ways of connecting the FM antenna to the antenna
input terminals: with a 300 _t twin-lead feeder or with a 75
coaxial cable.
To get the most from the receiver performance, a 75 _ coaxial ca-
ble is recommended since it is more immune than the twin-lead
feeder to noise and interference from external sources. If an FM
antenna has already been erected outdoors, connect it, referring
to the figure.
GROUNDING
Grounding is recommended if reception of FM programs is im-
paired by noise. To ground, connect a thick polyvinyl insulated
wire to the GND terminal and attach the other end to a metal
water pipe or grounding bar or wind it around a copper plate and
bury it.
NOTE:
Never connect a wire to a gas pipe for grounding since sparks
may ignite the gas.
EXTERNAL AM ANTENNA
If it is not possible to obtain adequate AM reception even by
changing the orientation of the AM loop antenna, a separate in-
door antenna, or an outdoor antenna should be installed.
INDOOR AM ANTENNA
Use a polyvinyl insulated wire (5 - 6m:17 - 20 feet) and con-
nect one end to the AM antenna terminal and affix the other end
to the wall or ceiling, as high as possible.
OUTDOOR AM ANTENNA
If reception quality is not improved sufficiently even when an in-
door antenna is used, a polyvinyl insulated wire should be in-
stalled outside and fixed in place.
NOTE:
Do not detach the AM loop antenna when using an indoor or an
outdoor AM antenna.
