OPERATING THEORY
Electromagnetic radiation which has frequencies of 20,000
Hz (20 kHz*) and above is called radio frequency (RF) energy
because it is useful in radio transmissions. The IC-R10 re-
ceives RF energy from 0.5 MHz to 1300 MHz* and converts it
into audio frequency (AF) energy which in turn actuates a
loudspeaker to create sound waves. AF energy is in the
range of 20 to 20,000 Hz.
*kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbreviation
of megahertz or 1,000,000 hertz, where hertz is a unit of frequency.

OPERATING NOTES
The IC-R10 may receives its own oscillated frequency, result-
ing in no reception or only noise reception, on some frequen-
cies.
The IC-R10 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.
