results will be obtained with a highly directional
FM antenna used with a rotator. Adjust the posi-
tion of the antenna until the best reception is
obtained.
A 75-ohm matched dipole antenna supplied
with your MR 7083 may be used in urban or in
high signal strength areas. The flexibility of the
thin wire assembly permits it to be placed under
a rug, tacked behind the stereo, or placed in any
other convenient location. In some cases, it may
be necessary to position the antenna for best
signal reception. Avoid locating this antenna next
to other wires or metal objects. An indoor
antenna may not prove effective in houses having
metal siding or metal insulation.
Although a 75-ohm coaxial feedline offers the
best noise and multipath rejection, many
antennas use 300-ohm twin lead. In this case, use
a matching transformer (balum) to convert a
300-ohm antenna to the 75-ohm input impedance
of the tuner.
6. SCOPE OUTPUT
The Horizontal output is the FM detector
output and provides frequency deviation output
for FM reception. The Verical output is from
amplitude detectors and provides signal strength
output for both FM and AM. An oscilloscope may
be connected for viewing FM multipath, signal
strength, and other waveforms.
7. AC POWER
Plug the AC power cord into a 120 volt 50/60 Hz
wall outlet. The plug blades are polarized so be
certain the plug is fully inserted in the outlet to
prevent blade exposure.
CAUTION: TO PREVENT ELECTRIC SHOCK, DO
NOT USE THE (POLARIZED) PLUG ON THIS UNIT
WITH AN EXTENSION CORD, RECEPTACLE, OR
OTHER OUTLET UNLESS THE BLADES CAN BE
FULLY INSERTED TO PREVENT BLADE EXPOSURE.
