NSTALLATION § OPERATING INSTRUCTIONS
ANTENNAS
For
shortwave
reception, it is necessary to connect a
length of wire (at least 10 feet long) to the screw terminal
located on the radio rear panel.
A commercial shortwave
antenna is recommended for best results.
No outside antenna
is normally required for standard
broadcast
station
reception.
A loop antenna for receiving
broadcast stations is built into the radio. If the radio is lo¬
cated at a considerable distance from broadcast stations, it
may
be
necessary
to secure
additional signal pick-up by
using an external antenna. The shortwave antenna wire may
byused for additional pick-up of standard broadcast stations;
leave the wire connected to the shortwave terminal screw
and wind two turns of the wire in the slots located at the top
of the radio rear panel.
CAUTION:
Do not connect antenna or chassis to water
pipe, radiator or other ground.

and volume control are combined and operated with the left-
hand knob.
If the radio does not operate from a DC power

after
being

When operating from
AC power lines,
reception can sometimes be improved by
reversing the power cord in the power outlet.
