POWER

lINE CORD. The receiver has an ac line cord terminated
in a three-prong plug. Connect the plug to a three-wire
grounded outlet providing a nominal 120 vac. 60 Hz power
source. If only a two-wire outlet is available, use an adapter
(such as Leviton No. 5017! to convert the outlet for use
with three-wire plugs.

AUXILIARY POWER RECEPTACLE. The rear of the Model
RM300 has an ac receptacle for supplying power to another
component in the system. This receptacle is controlled by
the power switch and any component connected to this
receptacle can be turned on and off by the POWER switch
on the Model RM300. Do not connect any component that
require: more than 575 watts 10 this receptacle.

ANTENNAS

PM "ME ANTENNA. The RM300 is shipped with the FM
line antenna connected to the FM terminal of the insulated
antenna strip on the rear of the unit. This antenna is ade-
quate for normal or strong signal areas. For best reception,
completely unwind the line cord. placing as much of it as
possible in a horizontal position away from metallic objects.

EXTERNAL FM ANTENNA

IMPORTANT

Always disconnect the FM Line Antenna when
using an external FM antenna.

For improved reception, particularly in weak signal areas
or for receivers mounted in racks. installation of an outdoor
FM or T" antenna is necessary. If you are installing a
standard SOC-ohm antenna system. connect the twin-lead
transmission line as shown in figure 2. [I conditions require
use of a coaxial transmission line. such as RG-ll/U or
RG-59/U. connect the cable as shown in figure 3. Coaxial
cable must be used when the transmission line is run in
conduit.

For optimum performance. a separate FM antenna is
recommended. If a TV antenna must be used for both FM
and TV reception, install an FM signal splitter at the end
of the transmission line. as shown in figure 4.

AM ANTENNA. A high-O. ferrite Ioopstick antenna is
located on the chassis for receiving normal or strong AM
signals. No connections are necessary for AM reception
with this antenna. For weak signal areas or for receivers
enclosed in a metal rack. connect a standard outdoor an-
tenna to the AM terminal. as shown in figure 5.
