Output
Signals from the OUTPUT jacks are fed to the amplifier.
Connection cables should be plugged to the amplifier TUNER
jacks. Shielded cables terminated at both ends with standard
phono plugs are supplied with this tuner.
Power cord
A low power is supplied to the memory to retain the memory
contents when the POWER switch is set to OFF. Even when
the power cord is disconnected from the AC outlet, the
memory is backed up. The memory contents are retained for
about three days.
To connect the power cord to the amplifier AC outlet, use the
unswitched outlet.
Ground
For maximum safety and minimum interference connect the
GND terminal to a good earth ground if practicable.
A good earth ground is a cold water pipe or a metal stake
driven into moist earth. However, never use a gas pipe for this
purpose.
FM indoor antenna
Connect the T-shaped indoor antenna (aupplied) to the 750
FM ANTENNA terminals as shown in System corfnections
diagram. Spread the two arms that form the top of the ''T''
horizontally and hold them against convenient wall surfaces.
4 KT-990D (k)
Try several locations for best results on your favorite stations.
Tape the antenna in place where the best compromise is
found between listening results and appearance.
FM outdoor antenna
Consult with your dealer or service man about the best
method of selecting and erecting an outdoor FM antenna. The
choice of lead-in (feeder) wire is also important. The flat
ribbon-shaped twin lead performs well electrically, is cheaper
and is somewhat easier to handle in routing through windows
and around rooms. Coaxial cable is more expensive, does a
much better job of minimizing interference, is less prone to
the effects of weather and close-by metal objects, and is
nearly as good a signal conductor as the ribbon type wire. T he
latter is particularly true of foam-type coaxial cables. Coaxial
cable is somewhat more difficult to install at the point where
the cable enters the building. If coaxial cable is selected,
make sure the antenna is designed to drive that type of cable.
In many cases a matching transformer (balun) must be used
to connect the antenna terminals to the coaxial cable.
750 coaxial cable connection
After stripping the end of your coaxial cable, mount the sup-
plied 750/3000 FM antenna adapter on the cable as shown.
Then insert the plug into the 750 ANTENNA terminal onthe
rear panel as whown in System connections diagram.
