sure the antenna system is grounded so as to pro-
vide some protection against voltage surges and
built up static charges.
In the U.S.A. section 810 of the National Electri-
cal Code, ANSI/NFPA No. 70-1284, provides
information with respect to proper grounding of
the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna dis-
charge unit, connection to grounding electrodes,
and requirements for the grounding electrode. See
Fig. A.
CART — An appliance and cart combination should be
moved with care. Quick stops, excessive force,
and uneven surfaces may cause the appliance and
cart combination to overturn.

HINTS FOR BETTER RECEPTION
OUTDOOR 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 special-
purpose FM antenna be installed. In weak signal areas, a
multi-element antenna should be used.
NOTE:
Consult your dealer as to the selection and actual installation of the
FM antenna.
FM ANTENNA CONNECTIONS
There are two ways of connecting the FM antenna to the
antenna input terminals: with a 300Q twin-lead feeder or
witha 7592 coaxial cable. If full justice is to be done to the
tuner's performance, a 750 coaxial cable 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 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.
OUTDOOR AM ANTENNAS
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 irístalled.
INDOOR AM ANTENNA
Use a vinyl 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 out-
door AM antenna.

FM reception
* Accessory T-type antenna remains bundied up or
it is not pointing in the right direction.
e Stretch both ends of antenna taut and turn to a
direction yielding optimum reception.
® Weak broadcasting station signals.
* Replace accessory T-type antenna with outdoor
FM antenna.
* Noise picked up from other equipment (or, in
particular, from passing automobiles}.
® ““Multipath’’ results when signals from broadcasting
station entering antenna directry are mixed with
signals which have been reflected by mountains
or high buildings on their way to antenna. This
results in distorted sound and noise.
e Try altering direction and mounting position-of
antenna. If an outdoor antenna has been
erected, place it as far away as possible from
passing traffic and use a 75 Q coaxial cable for
connections.
AM reception
* AM antenna not pointing in right direction.
e Change AM antenna's direction and find a position
where reception is improved.
e Weak broadcasting station signals.
e Erect outdoor AM antenna or connect ground
wire.
* Noise being picked up from other equipment
(especially electrical appliances using motor or
fluorescent lights).
e Stop using the appliances generating noise or
remove them from the vicinity of stereo equipment.
No auto tuning.
(FM reception)
e Input signals are not strong enough.
* |f an accessory T-type antenna is used, change over
to an outdoor antenna.
