HINTS FOR BETTER RECEPTION
EXTERNAL FM ANTENNA I
The main advantage of FM over AM is the quality of the
broadcast signal. In order to benefit fully from the high signal
quality of FM broadcasts, it is recommended that a special-
purpose FM antenna be installed. In weak signal areas, a multi-
element (3-element, 5-element, 7-element) antenna should
be used.
[GROUNDING
Grounding is recommended if reception of FM programs is
impaired 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
_gnitethe 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
indoor antenna or an outdoor antenna should be installed.
INDOOR AM ANTENNA
Use a vinyl-insulated wire 5 to 6 meters long (15 to 18 feet)
and connect 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
indoor antenna is used, a vinyl-insulated wire should be
installed outside and fixed in place.
NOTE:
Do not detach the AM loop antenna when using an indoor or an
outdoor AM antenna.
