HINTS FOR BETTER RECEPTION
| EXTERNAL FM ANTENNA
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 speciai-purpose FM antenna
be instalied. 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
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 indoor
antenna or an outdoor antenna should be instailed.
iNDOCR AM ANTENNA
Use a vinyi-insulated wire (5 — 6 m} 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.
